A flaw was found in moodle where ID numbers displayed when bulk allocating markers to assignments required additional sanitizing to prevent a stored XSS risk.
CVE-2022-1949 3 Fedoraproject, Port389, Redhat 4 Fedora, 389-ds-base, Directory Server and 1 more 2022-06-13 5.0 MEDIUM 7.5 HIGH
An access control bypass vulnerability found in 389-ds-base. That mishandling of the filter that would yield incorrect results, but as that has progressed, can be determined that it actually is an access control bypass. This may allow any remote unauthenticated user to issue a filter that allows searching for database items they do not have access to, including but not limited to potentially userPassword hashes and other sensitive data.
CVE-2020-6062 4 Canonical, Coturn Project, Debian and 1 more 4 Ubuntu Linux, Coturn, Debian Linux and 1 more 2022-06-07 5.0 MEDIUM 7.5 HIGH
An exploitable denial-of-service vulnerability exists in the way CoTURN 4.5.1.1 web server parses POST requests. A specially crafted HTTP POST request can lead to server crash and denial of service. An attacker needs to send an HTTP request to trigger this vulnerability.
CVE-2020-6070 2 F2fs-tools Project, Fedoraproject 2 F2fs-tools, Fedora 2022-06-07 6.8 MEDIUM 7.8 HIGH
An exploitable code execution vulnerability exists in the file system checking functionality of fsck.f2fs 1.12.0. A specially crafted f2fs file can cause a logic flaw and out-of-bounds heap operations, resulting in code execution. An attacker can provide a malicious file to trigger this vulnerability.
CVE-2020-6061 4 Canonical, Coturn Project, Debian and 1 more 4 Ubuntu Linux, Coturn, Debian Linux and 1 more 2022-06-07 7.5 HIGH 9.8 CRITICAL
An exploitable heap out-of-bounds read vulnerability exists in the way CoTURN 4.5.1.1 web server parses POST requests. A specially crafted HTTP POST request can lead to information leaks and other misbehavior. An attacker needs to send an HTTPS request to trigger this vulnerability.
CVE-2022-29217 2 Fedoraproject, Pyjwt Project 2 Fedora, Pyjwt 2022-06-07 5.0 MEDIUM 7.5 HIGH
PyJWT is a Python implementation of RFC 7519. PyJWT supports multiple different JWT signing algorithms. With JWT, an attacker submitting the JWT token can choose the used signing algorithm. The PyJWT library requires that the application chooses what algorithms are supported. The application can specify `jwt.algorithms.get_default_algorithms()` to get support for all algorithms, or specify a single algorithm. The issue is not that big as `algorithms=jwt.algorithms.get_default_algorithms()` has to be used. Users should upgrade to v2.4.0 to receive a patch for this issue. As a workaround, always be explicit with the algorithms that are accepted and expected when decoding.
CVE-2020-28242 3 Asterisk, Debian, Fedoraproject 4 Certified Asterisk, Open Source, Debian Linux and 1 more 2022-06-04 4.0 MEDIUM 6.5 MEDIUM
An issue was discovered in Asterisk Open Source 13.x before 13.37.1, 16.x before 16.14.1, 17.x before 17.8.1, and 18.x before 18.0.1 and Certified Asterisk before 16.8-cert5. If Asterisk is challenged on an outbound INVITE and the nonce is changed in each response, Asterisk will continually send INVITEs in a loop. This causes Asterisk to consume more and more memory since the transaction will never terminate (even if the call is hung up), ultimately leading to a restart or shutdown of Asterisk. Outbound authentication must be configured on the endpoint for this to occur.
CVE-2015-5239 5 Arista, Canonical, Fedoraproject and 2 more 8 Eos, Ubuntu Linux, Fedora and 5 more 2022-06-04 4.0 MEDIUM 6.5 MEDIUM
Integer overflow in the VNC display driver in QEMU before 2.1.0 allows attachers to cause a denial of service (process crash) via a CLIENT_CUT_TEXT message, which triggers an infinite loop.
CVE-2020-8139 2 Fedoraproject, Nextcloud 2 Fedora, Nextcloud Server 2022-06-03 4.0 MEDIUM 6.5 MEDIUM
A missing access control check in Nextcloud Server < 18.0.1, < 17.0.4, and < 16.0.9 causes hide-download shares to be downloadable when appending /download to the URL.
CVE-2021-22212 2 Fedoraproject, Ntpsec 2 Fedora, Ntpsec 2022-06-03 5.8 MEDIUM 7.4 HIGH
ntpkeygen can generate keys that ntpd fails to parse. NTPsec 1.2.0 allows ntpkeygen to generate keys with '#' characters. ntpd then either pads, shortens the key, or fails to load these keys entirely, depending on the key type and the placement of the '#'. This results in the administrator not being able to use the keys as expected or the keys are shorter than expected and easier to brute-force, possibly resulting in MITM attacks between ntp clients and ntp servers. For short AES128 keys, ntpd generates a warning that it is padding them.
CVE-2021-29470 2 Exiv2, Fedoraproject 2 Exiv2, Fedora 2022-06-03 4.3 MEDIUM 6.5 MEDIUM
Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. An out-of-bounds read was found in Exiv2 versions v0.27.3 and earlier. The out-of-bounds read is triggered when Exiv2 is used to write metadata into a crafted image file. An attacker could potentially exploit the vulnerability to cause a denial of service by crashing Exiv2, if they can trick the victim into running Exiv2 on a crafted image file. Note that this bug is only triggered when writing the metadata, which is a less frequently used Exiv2 operation than reading the metadata. For example, to trigger the bug in the Exiv2 command-line application, you need to add an extra command-line argument such as insert. The bug is fixed in version v0.27.4.
CVE-2021-26931 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2022-06-03 1.9 LOW 5.5 MEDIUM
An issue was discovered in the Linux kernel 2.6.39 through 5.10.16, as used in Xen. Block, net, and SCSI backends consider certain errors a plain bug, deliberately causing a kernel crash. For errors potentially being at least under the influence of guests (such as out of memory conditions), it isn't correct to assume a plain bug. Memory allocations potentially causing such crashes occur only when Linux is running in PV mode, though. This affects drivers/block/xen-blkback/blkback.c and drivers/xen/xen-scsiback.c.
CVE-2021-29478 2 Fedoraproject, Redislabs 2 Fedora, Redis 2022-06-03 6.0 MEDIUM 8.8 HIGH
Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache, and message broker. An integer overflow bug in Redis 6.2 before 6.2.3 could be exploited to corrupt the heap and potentially result with remote code execution. Redis 6.0 and earlier are not directly affected by this issue. The problem is fixed in version 6.2.3. An additional workaround to mitigate the problem without patching the `redis-server` executable is to prevent users from modifying the `set-max-intset-entries` configuration parameter. This can be done using ACL to restrict unprivileged users from using the `CONFIG SET` command.
CVE-2021-29477 2 Fedoraproject, Redislabs 2 Fedora, Redis 2022-06-03 6.5 MEDIUM 8.8 HIGH
Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache, and message broker. An integer overflow bug in Redis version 6.0 or newer could be exploited using the `STRALGO LCS` command to corrupt the heap and potentially result with remote code execution. The problem is fixed in version 6.2.3 and 6.0.13. An additional workaround to mitigate the problem without patching the redis-server executable is to use ACL configuration to prevent clients from using the `STRALGO LCS` command.
CVE-2021-33194 2 Fedoraproject, Golang 2 Fedora, Go 2022-06-03 5.0 MEDIUM 7.5 HIGH
golang.org/x/net before v0.0.0-20210520170846-37e1c6afe023 allows attackers to cause a denial of service (infinite loop) via crafted ParseFragment input.
CVE-2021-3421 3 Fedoraproject, Redhat, Rpm 3 Fedora, Enterprise Linux, Rpm 2022-06-03 4.3 MEDIUM 5.5 MEDIUM
A flaw was found in the RPM package in the read functionality. This flaw allows an attacker who can convince a victim to install a seemingly verifiable package or compromise an RPM repository, to cause RPM database corruption. The highest threat from this vulnerability is to data integrity. This flaw affects RPM versions before 4.17.0-alpha.
