CVE-2020-14929 3 Alpine Project, Debian, Fedoraproject 3 Alpine, Debian Linux, Fedora 2023-01-27 5.0 MEDIUM 7.5 HIGH
Alpine before 2.23 silently proceeds to use an insecure connection after a /tls is sent in certain circumstances involving PREAUTH, which is a less secure behavior than the alternative of closing the connection and letting the user decide what they would like to do.
CVE-2020-5238 2 Fedoraproject, Github Flavored Markdown Project 2 Fedora, Github Flavored Markdown 2023-01-27 4.0 MEDIUM 6.5 MEDIUM
The table extension in GitHub Flavored Markdown before version 0.29.0.gfm.1 takes O(n * n) time to parse certain inputs. An attacker could craft a markdown table which would take an unreasonably long time to process, causing a denial of service. This issue does not affect the upstream cmark project. The issue has been fixed in version 0.29.0.gfm.1.
CVE-2020-13753 6 Canonical, Debian, Fedoraproject and 3 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2023-01-27 7.5 HIGH 10.0 CRITICAL
The bubblewrap sandbox of WebKitGTK and WPE WebKit, prior to 2.28.3, failed to properly block access to CLONE_NEWUSER and the TIOCSTI ioctl. CLONE_NEWUSER could potentially be used to confuse xdg-desktop-portal, which allows access outside the sandbox. TIOCSTI can be used to directly execute commands outside the sandbox by writing to the controlling terminal's input buffer, similar to CVE-2017-5226.
CVE-2017-9106 2 Fedoraproject, Gnu 2 Fedora, Adns 2023-01-27 5.0 MEDIUM 7.5 HIGH
An issue was discovered in adns before 1.5.2. adns_rr_info mishandles a bogus *datap. The general pattern for formatting integers is to sprintf into a fixed-size buffer. This is correct if the input is in the right range; if it isn't, the buffer may be overrun (depending on the sizes of the types on the current platform). Of course the inputs ought to be right. And there are pointers in there too, so perhaps one could say that the caller ought to check these things. It may be better to require the caller to make the pointer structure right, but to have the code here be defensive about (and tolerate with an error but without crashing) out-of-range integer values. So: it should defend each of these integer conversion sites with a check for the actual permitted range, and return adns_s_invaliddata if not. The lack of this check causes the SOA sign extension bug to be a serious security problem: the sign extended SOA value is out of range, and overruns the buffer when reconverted. This is related to sign extending SOA 32-bit integer fields, and use of a signed data type.
CVE-2017-9107 2 Fedoraproject, Gnu 2 Fedora, Adns 2023-01-27 5.0 MEDIUM 7.5 HIGH
An issue was discovered in adns before 1.5.2. It overruns reading a buffer if a domain ends with backslash. If the query domain ended with \, and adns_qf_quoteok_query was specified, qdparselabel would read additional bytes from the buffer and try to treat them as the escape sequence. It would depart the input buffer and start processing many bytes of arbitrary heap data as if it were the query domain. Eventually it would run out of input or find some other kind of error, and declare the query domain invalid. But before then it might outrun available memory and crash. In principle this could be a denial of service attack.
CVE-2019-13033 3 Cisofy, Debian, Fedoraproject 3 Lynis, Debian Linux, Fedora 2023-01-27 2.1 LOW 3.3 LOW
In CISOfy Lynis 2.x through 2.7.5, the license key can be obtained by looking at the process list when a data upload is being performed. This license can be used to upload data to a central Lynis server. Although no data can be extracted by knowing the license key, it may be possible to upload the data of additional scans.
CVE-2022-4144 3 Fedoraproject, Qemu, Redhat 4 Extra Packages For Enterprise Linux, Fedora, Qemu and 1 more 2023-01-27 N/A 6.5 MEDIUM
An out-of-bounds read flaw was found in the QXL display device emulation in QEMU. The qxl_phys2virt() function does not check the size of the structure pointed to by the guest physical address, potentially reading past the end of the bar space into adjacent pages. A malicious guest user could use this flaw to crash the QEMU process on the host causing a denial of service condition.
CVE-2022-30674 4 Adobe, Apple, Fedoraproject and 1 more 4 Indesign, Macos, Fedora and 1 more 2023-01-27 N/A 5.5 MEDIUM
Adobe InDesign versions 16.4.2 (and earlier) and 17.3 (and earlier) are affected by an out-of-bounds read vulnerability that could lead to disclosure of sensitive memory. An attacker could leverage this vulnerability to bypass mitigations such as ASLR. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
CVE-2022-40617 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2023-01-27 N/A 7.5 HIGH
strongSwan before 5.9.8 allows remote attackers to cause a denial of service in the revocation plugin by sending a crafted end-entity (and intermediate CA) certificate that contains a CRL/OCSP URL that points to a server (under the attacker's control) that doesn't properly respond but (for example) just does nothing after the initial TCP handshake, or sends an excessive amount of application data.
CVE-2017-9109 3 Fedoraproject, Gnu, Opensuse 3 Fedora, Adns, Leap 2023-01-27 7.5 HIGH 9.8 CRITICAL
An issue was discovered in adns before 1.5.2. It fails to ignore apparent answers before the first RR that was found the first time. when this is fixed, the second answer scan finds the same RRs at the first. Otherwise, adns can be confused by interleaving answers for the CNAME target, with the CNAME itself. In that case the answer data structure (on the heap) can be overrun. With this fixed, it prefers to look only at the answer RRs which come after the CNAME, which is at least arguably correct.
CVE-2017-9103 3 Fedoraproject, Gnu, Opensuse 3 Fedora, Adns, Leap 2023-01-27 7.5 HIGH 9.8 CRITICAL
An issue was discovered in adns before 1.5.2. pap_mailbox822 does not properly check st from adns__findlabel_next. Without this, an uninitialised stack value can be used as the first label length. Depending on the circumstances, an attacker might be able to trick adns into crashing the calling program, leaking aspects of the contents of some of its memory, causing it to allocate lots of memory, or perhaps overrunning a buffer. This is only possible with applications which make non-raw queries for SOA or RP records.
CVE-2017-9104 3 Fedoraproject, Gnu, Opensuse 3 Fedora, Adns, Leap 2023-01-27 7.5 HIGH 9.8 CRITICAL
An issue was discovered in adns before 1.5.2. It hangs, eating CPU, if a compression pointer loop is encountered.
CVE-2017-9108 3 Fedoraproject, Gnu, Opensuse 3 Fedora, Adns, Leap 2023-01-27 5.0 MEDIUM 7.5 HIGH
An issue was discovered in adns before 1.5.2. adnshost mishandles a missing final newline on a stdin read. It is wrong to increment used as well as setting r, since used is incremented according to r, later. Rather one should be doing what read() would have done. Without this fix, adnshost may read and process one byte beyond the buffer, perhaps crashing or perhaps somehow leaking the value of that byte.
CVE-2017-9105 2 Fedoraproject, Gnu 2 Fedora, Adns 2023-01-27 7.5 HIGH 8.8 HIGH
An issue was discovered in adns before 1.5.2. It corrupts a pointer when a nameserver speaks first because of a wrong number of pointer dereferences. This bug may well be exploitable as a remote code execution.
CVE-2020-14148 3 Barton, Debian, Fedoraproject 3 Ngircd, Debian Linux, Fedora 2023-01-27 5.0 MEDIUM 7.5 HIGH
The Server-Server protocol implementation in ngIRCd before 26~rc2 allows an out-of-bounds access, as demonstrated by the IRC_NJOIN() function.
CVE-2020-13999 2 Fedoraproject, Libemf Project 2 Fedora, Libemf 2023-01-27 4.3 MEDIUM 5.5 MEDIUM
ScaleViewPortExtEx in libemf.cpp in libEMF (aka ECMA-234 Metafile Library) 1.0.12 allows an integer overflow and denial of service via a crafted EMF file.
CVE-2020-4046 3 Debian, Fedoraproject, Wordpress 3 Debian Linux, Fedora, Wordpress 2023-01-27 3.5 LOW 5.4 MEDIUM
In affected versions of WordPress, users with low privileges (like contributors and authors) can use the embed block in a certain way to inject unfiltered HTML in the block editor. When affected posts are viewed by a higher privileged user, this could lead to script execution in the editor/wp-admin. This has been patched in version 5.4.2, along with all the previously affected versions via a minor release (5.3.4, 5.2.7, 5.1.6, 5.0.10, 4.9.15, 4.8.14, 4.7.18, 4.6.19, 4.5.22, 4.4.23, 4.3.24, 4.2.28, 4.1.31, 4.0.31, 3.9.32, 3.8.34, 3.7.34).
CVE-2020-13775 2 Fedoraproject, Znc 2 Fedora, Znc 2023-01-27 3.5 LOW 6.5 MEDIUM
ZNC 1.8.0 up to 1.8.1-rc1 allows authenticated users to trigger an application crash (with a NULL pointer dereference) if echo-message is not enabled and there is no network.
CVE-2020-12823 4 Debian, Fedoraproject, Infradead and 1 more 4 Debian Linux, Fedora, Openconnect and 1 more 2023-01-27 7.5 HIGH 9.8 CRITICAL
OpenConnect 8.09 has a buffer overflow, causing a denial of service (application crash) or possibly unspecified other impact, via crafted certificate data to get_cert_name in gnutls.c.
CVE-2020-1983 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2023-01-27 2.1 LOW 6.5 MEDIUM
A use after free vulnerability in ip_reass() in ip_input.c of libslirp 4.2.0 and prior releases allows crafted packets to cause a denial of service.
