| CVE-2020-25687 | 3 Debian, Fedoraproject, Thekelleys | 3 Debian Linux, Fedora, Dnsmasq | 2021-03-26 | 7.1 HIGH | 5.9 MEDIUM |
| A flaw was found in dnsmasq before version 2.83. A heap-based buffer overflow was discovered in dnsmasq when DNSSEC is enabled and before it validates the received DNS entries. This flaw allows a remote attacker, who can create valid DNS replies, to cause an overflow in a heap-allocated memory. This flaw is caused by the lack of length checks in rfc1035.c:extract_name(), which could be abused to make the code execute memcpy() with a negative size in sort_rrset() and cause a crash in dnsmasq, resulting in a denial of service. The highest threat from this vulnerability is to system availability. | |||||

| CVE-2020-25682 | 3 Debian, Fedoraproject, Thekelleys | 3 Debian Linux, Fedora, Dnsmasq | 2021-03-26 | 8.3 HIGH | 8.1 HIGH |
| A flaw was found in dnsmasq before 2.83. A buffer overflow vulnerability was discovered in the way dnsmasq extract names from DNS packets before validating them with DNSSEC data. An attacker on the network, who can create valid DNS replies, could use this flaw to cause an overflow with arbitrary data in a heap-allocated memory, possibly executing code on the machine. The flaw is in the rfc1035.c:extract_name() function, which writes data to the memory pointed by name assuming MAXDNAME*2 bytes are available in the buffer. However, in some code execution paths, it is possible extract_name() gets passed an offset from the base buffer, thus reducing, in practice, the number of available bytes that can be written in the buffer. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | |||||
| CVE-2020-25681 | 3 Debian, Fedoraproject, Thekelleys | 3 Debian Linux, Fedora, Dnsmasq | 2021-03-26 | 8.3 HIGH | 8.1 HIGH |
| A flaw was found in dnsmasq before version 2.83. A heap-based buffer overflow was discovered in the way RRSets are sorted before validating with DNSSEC data. An attacker on the network, who can forge DNS replies such as that they are accepted as valid, could use this flaw to cause a buffer overflow with arbitrary data in a heap memory segment, possibly executing code on the machine. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | |||||
| CVE-2019-10196 | 3 Fedoraproject, Http-proxy-agent Project, Redhat | 4 Fedora, Http-proxy-agent, Enterprise Linux and 1 more | 2021-03-25 | 9.0 HIGH | 9.8 CRITICAL |
| A flaw was found in http-proxy-agent, prior to version 2.1.0. It was discovered http-proxy-agent passes an auth option to the Buffer constructor without proper sanitization. This could result in a Denial of Service through the usage of all available CPU resources and data exposure through an uninitialized memory leak in setups where an attacker could submit typed input to the auth parameter. | |||||

| CVE-2021-3178 | 3 Debian, Fedoraproject, Linux | 3 Debian Linux, Fedora, Linux Kernel | 2021-03-25 | 5.5 MEDIUM | 6.5 MEDIUM |
| ** DISPUTED ** fs/nfsd/nfs3xdr.c in the Linux kernel through 5.10.8, when there is an NFS export of a subdirectory of a filesystem, allows remote attackers to traverse to other parts of the filesystem via READDIRPLUS. NOTE: some parties argue that such a subdirectory export is not intended to prevent this attack; see also the exports(5) no_subtree_check default behavior. | |||||
| CVE-2021-21381 | 3 Debian, Fedoraproject, Flatpak | 3 Debian Linux, Fedora, Flatpak | 2021-03-24 | 5.8 MEDIUM | 8.2 HIGH |
| Flatpak is a system for building, distributing, and running sandboxed desktop applications on Linux. In Flatpack since version 0.9.4 and before version 1.10.2 has a vulnerability in the "file forwarding" feature which can be used by an attacker to gain access to files that would not ordinarily be allowed by the app's permissions. By putting the special tokens `@@` and/or `@@u` in the Exec field of a Flatpak app's .desktop file, a malicious app publisher can trick flatpak into behaving as though the user had chosen to open a target file with their Flatpak app, which automatically makes that file available to the Flatpak app. This is fixed in version 1.10.2. A minimal solution is the first commit "`Disallow @@ and @@U usage in desktop files`". The follow-up commits "`dir: Reserve the whole @@ prefix`" and "`dir: Refuse to export .desktop files with suspicious uses of @@ tokens`" are recommended, but not strictly required. As a workaround, avoid installing Flatpak apps from untrusted sources, or check the contents of the exported `.desktop` files in `exports/share/applications/*.desktop` (typically `~/.local/share/flatpak/exports/share/applications/*.desktop` and `/var/lib/flatpak/exports/share/applications/*.desktop`) to make sure that literal filenames do not follow `@@` or `@@u`. | |||||
| CVE-2021-3420 | 2 Fedoraproject, Newlib Project | 2 Fedora, Newlib | 2021-03-24 | 7.5 HIGH | 9.8 CRITICAL |
| A flaw was found in newlib in versions prior to 4.0.0. Improper overflow validation in the memory allocation functions mEMALIGn, pvALLOc, nano_memalign, nano_valloc, nano_pvalloc could case an integer overflow, leading to an allocation of a small buffer and then to a heap-based buffer overflow. | |||||
| CVE-2021-20179 | 3 Dogtagpki, Fedoraproject, Redhat | 4 Dogtagpki, Fedora, Certificate System and 1 more | 2021-03-23 | 5.5 MEDIUM | 8.1 HIGH |
| A flaw was found in pki-core. An attacker who has successfully compromised a key could use this flaw to renew the corresponding certificate over and over again, as long as it is not explicitly revoked. The highest threat from this vulnerability is to data confidentiality and integrity. | |||||
| CVE-2021-26927 | 2 Fedoraproject, Jasper Project | 2 Fedora, Jasper | 2021-03-23 | 4.3 MEDIUM | 5.5 MEDIUM |
| A flaw was found in jasper before 2.0.25. A null pointer dereference in jp2_decode in jp2_dec.c may lead to program crash and denial of service. | |||||
| CVE-2021-20282 | 2 Fedoraproject, Moodle | 2 Fedora, Moodle | 2021-03-23 | 5.0 MEDIUM | 5.3 MEDIUM |
| When creating a user account, it was possible to verify the account without having access to the verification email link/secret in moodle before 3.10.2, 3.9.5, 3.8.8, 3.5.17. | |||||
| CVE-2021-20279 | 2 Fedoraproject, Moodle | 2 Fedora, Moodle | 2021-03-23 | 3.5 LOW | 5.4 MEDIUM |
| The ID number user profile field required additional sanitizing to prevent a stored XSS risk in moodle before 3.10.2, 3.9.5, 3.8.8, 3.5.17. | |||||
| CVE-2021-23351 | 2 Fedoraproject, Go-proxyproto Project | 2 Fedora, Go-proxyproto | 2021-03-23 | 4.0 MEDIUM | 4.9 MEDIUM |
| The package github.com/pires/go-proxyproto before 0.5.0 are vulnerable to Denial of Service (DoS) via the parseVersion1() function. The reader in this package is a default bufio.Reader wrapping a net.Conn. It will read from the connection until it finds a newline. Since no limits are implemented in the code, a deliberately malformed V1 header could be used to exhaust memory in a server process using this code - and create a DoS. This can be exploited by sending a stream starting with PROXY and continuing to send data (which does not contain a newline) until the target stops acknowledging. The risk here is small, because only trusted sources should be allowed to send proxy protocol headers. | |||||
| CVE-2021-21367 | 2 Elementary, Fedoraproject | 2 Switchboard Bluetooth Plug, Fedora | 2021-03-23 | 4.3 MEDIUM | 8.1 HIGH |
| Switchboard Bluetooth Plug for elementary OS from version 2.3.0 and before version version 2.3.5 has an incorrect authorization vulnerability. When the Bluetooth plug is running (in discoverable mode), Bluetooth service requests and pairing requests are automatically accepted, allowing physically proximate attackers to pair with a device running an affected version of switchboard-plug-bluetooth without the active consent of the user. By default, elementary OS doesn't expose any services via Bluetooth that allow information to be extracted by paired Bluetooth devices. However, if such services (i.e. contact list sharing software) have been installed, it's possible that attackers have been able to extract data from such services without authorization. If no such services have been installed, attackers are only able to pair with a device running an affected version without authorization and then play audio out of the device or possibly present a HID device (keyboard, mouse, etc...) to control the device. As such, users should check the list of trusted/paired devices and remove any that are not 100% confirmed to be genuine. This is fixed in version 2.3.5. To reduce the likelihood of this vulnerability on an unpatched version, only open the Bluetooth plug for short intervals when absolutely necessary and preferably not in crowded public areas. To mitigate the risk entirely with unpatched versions, do not open the Bluetooth plug within switchboard at all, and use a different method for pairing devices if necessary (e.g. `bluetoothctl` CLI). | |||||
| CVE-2021-26926 | 2 Fedoraproject, Jasper Project | 2 Fedora, Jasper | 2021-03-22 | 5.8 MEDIUM | 7.1 HIGH |
| A flaw was found in jasper before 2.0.25. An out of bounds read issue was found in jp2_decode function whic may lead to disclosure of information or program crash. | |||||
| CVE-2020-35654 | 2 Fedoraproject, Python | 2 Fedora, Pillow | 2021-03-22 | 6.8 MEDIUM | 8.8 HIGH |
| In Pillow before 8.1.0, TiffDecode has a heap-based buffer overflow when decoding crafted YCbCr files because of certain interpretation conflicts with LibTIFF in RGBA mode. | |||||
| CVE-2020-29385 | 3 Canonical, Fedoraproject, Gnome | 3 Ubuntu Linux, Fedora, Gdk-pixbuf | 2021-03-22 | 4.3 MEDIUM | 5.5 MEDIUM |
| GNOME gdk-pixbuf (aka GdkPixbuf) before 2.42.2 allows a denial of service (infinite loop) in lzw.c in the function write_indexes. if c->self_code equals 10, self->code_table[10].extends will assign the value 11 to c. The next execution in the loop will assign self->code_table[11].extends to c, which will give the value of 10. This will make the loop run infinitely. This bug can, for example, be triggered by calling this function with a GIF image with LZW compression that is crafted in a special way. | |||||
| CVE-2019-16276 | 6 Debian, Fedoraproject, Golang and 3 more | 9 Debian Linux, Fedora, Go and 6 more | 2021-03-22 | 5.0 MEDIUM | 7.5 HIGH |
| Go before 1.12.10 and 1.13.x before 1.13.1 allow HTTP Request Smuggling. | |||||
