CVE-2019-11338 4 Canonical, Debian, Ffmpeg and 1 more 4 Ubuntu Linux, Debian Linux, Ffmpeg and 1 more 2022-10-07 6.8 MEDIUM 8.8 HIGH
libavcodec/hevcdec.c in FFmpeg 3.4 and 4.1.2 mishandles detection of duplicate first slices, which allows remote attackers to cause a denial of service (NULL pointer dereference and out-of-array access) or possibly have unspecified other impact via crafted HEVC data.
CVE-2020-8834 4 Canonical, Ibm, Linux and 1 more 4 Ubuntu Linux, Power8, Linux Kernel and 1 more 2022-10-07 4.9 MEDIUM 6.5 MEDIUM
KVM in the Linux kernel on Power8 processors has a conflicting use of HSTATE_HOST_R1 to store r1 state in kvmppc_hv_entry plus in kvmppc_{save,restore}_tm, leading to a stack corruption. Because of this, an attacker with the ability run code in kernel space of a guest VM can cause the host kernel to panic. There were two commits that, according to the reporter, introduced the vulnerability: f024ee098476 ("KVM: PPC: Book3S HV: Pull out TM state save/restore into separate procedures") 87a11bb6a7f7 ("KVM: PPC: Book3S HV: Work around XER[SO] bug in fake suspend mode") The former landed in 4.8, the latter in 4.17. This was fixed without realizing the impact in 4.18 with the following three commits, though it's believed the first is the only strictly necessary commit: 6f597c6b63b6 ("KVM: PPC: Book3S PR: Add guest MSR parameter for kvmppc_save_tm()/kvmppc_restore_tm()") 7b0e827c6970 ("KVM: PPC: Book3S HV: Factor fake-suspend handling out of kvmppc_save/restore_tm") 009c872a8bc4 ("KVM: PPC: Book3S PR: Move kvmppc_save_tm/kvmppc_restore_tm to separate file")
CVE-2020-8831 2 Apport Project, Canonical 2 Apport, Ubuntu Linux 2022-10-07 2.1 LOW 5.5 MEDIUM
Apport creates a world writable lock file with root ownership in the world writable /var/lock/apport directory. If the apport/ directory does not exist (this is not uncommon as /var/lock is a tmpfs), it will create the directory, otherwise it will simply continue execution using the existing directory. This allows for a symlink attack if an attacker were to create a symlink at /var/lock/apport, changing apport's lock file location. This file could then be used to escalate privileges, for example. Fixed in versions 2.20.1-0ubuntu2.23, 2.20.9-0ubuntu7.14, 2.20.11-0ubuntu8.8 and 2.20.11-0ubuntu22.
CVE-2020-8619 6 Canonical, Debian, Fedoraproject and 3 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2022-10-07 4.0 MEDIUM 4.9 MEDIUM
In ISC BIND9 versions BIND 9.11.14 -> 9.11.19, BIND 9.14.9 -> 9.14.12, BIND 9.16.0 -> 9.16.3, BIND Supported Preview Edition 9.11.14-S1 -> 9.11.19-S1: Unless a nameserver is providing authoritative service for one or more zones and at least one zone contains an empty non-terminal entry containing an asterisk ("*") character, this defect cannot be encountered. A would-be attacker who is allowed to change zone content could theoretically introduce such a record in order to exploit this condition to cause denial of service, though we consider the use of this vector unlikely because any such attack would require a significant privilege level and be easily traceable.
CVE-2020-8833 2 Apport Project, Canonical 2 Apport, Ubuntu Linux 2022-10-07 1.9 LOW 4.7 MEDIUM
Time-of-check Time-of-use Race Condition vulnerability on crash report ownership change in Apport allows for a possible privilege escalation opportunity. If fs.protected_symlinks is disabled, this can be exploited between the os.open and os.chown calls when the Apport cron script clears out crash files of size 0. A symlink with the same name as the deleted file can then be created upon which chown will be called, changing the file owner to root. Fixed in versions 2.20.1-0ubuntu2.23, 2.20.9-0ubuntu7.14, 2.20.11-0ubuntu8.8 and 2.20.11-0ubuntu22.
CVE-2019-1010315 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2022-10-07 4.3 MEDIUM 5.5 MEDIUM
WavPack 5.1 and earlier is affected by: CWE 369: Divide by Zero. The impact is: Divide by zero can lead to sudden crash of a software/service that tries to parse a .wav file. The component is: ParseDsdiffHeaderConfig (dsdiff.c:282). The attack vector is: Maliciously crafted .wav file. The fixed version is: After commit https://github.com/dbry/WavPack/commit/4c0faba32fddbd0745cbfaf1e1aeb3da5d35b9fc.
CVE-2019-11135 9 Canonical, Debian, Fedoraproject and 6 more 304 Ubuntu Linux, Debian Linux, Fedora and 301 more 2022-10-07 2.1 LOW 6.5 MEDIUM
TSX Asynchronous Abort condition on some CPUs utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access.
CVE-2020-14345 2 Canonical, X.org 2 Ubuntu Linux, X Server 2022-10-07 4.6 MEDIUM 7.8 HIGH
A flaw was found in X.Org Server before xorg-x11-server 1.20.9. An Out-Of-Bounds access in XkbSetNames function may lead to a privilege escalation vulnerability. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2019-11498 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2022-10-07 4.3 MEDIUM 6.5 MEDIUM
WavpackSetConfiguration64 in pack_utils.c in libwavpack.a in WavPack through 5.1.0 has a "Conditional jump or move depends on uninitialised value" condition, which might allow attackers to cause a denial of service (application crash) via a DFF file that lacks valid sample-rate data.
CVE-2019-17563 5 Apache, Canonical, Debian and 2 more 11 Tomcat, Ubuntu Linux, Debian Linux and 8 more 2022-10-07 5.1 MEDIUM 7.5 HIGH
When using FORM authentication with Apache Tomcat 9.0.0.M1 to 9.0.29, 8.5.0 to 8.5.49 and 7.0.0 to 7.0.98 there was a narrow window where an attacker could perform a session fixation attack. The window was considered too narrow for an exploit to be practical but, erring on the side of caution, this issue has been treated as a security vulnerability.
CVE-2020-24584 4 Canonical, Djangoproject, Fedoraproject and 1 more 4 Ubuntu Linux, Django, Fedora and 1 more 2022-10-07 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Django 2.2 before 2.2.16, 3.0 before 3.0.10, and 3.1 before 3.1.1 (when Python 3.7+ is used). The intermediate-level directories of the filesystem cache had the system's standard umask rather than 0o077.
CVE-2020-24583 4 Canonical, Djangoproject, Fedoraproject and 1 more 4 Ubuntu Linux, Django, Fedora and 1 more 2022-10-07 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Django 2.2 before 2.2.16, 3.0 before 3.0.10, and 3.1 before 3.1.1 (when Python 3.7+ is used). FILE_UPLOAD_DIRECTORY_PERMISSIONS mode was not applied to intermediate-level directories created in the process of uploading files. It was also not applied to intermediate-level collected static directories when using the collectstatic management command.
CVE-2020-8618 4 Canonical, Isc, Netapp and 1 more 4 Ubuntu Linux, Bind, Steelstore Cloud Integrated Storage and 1 more 2022-10-07 4.0 MEDIUM 4.9 MEDIUM
An attacker who is permitted to send zone data to a server via zone transfer can exploit this to intentionally trigger the assertion failure with a specially constructed zone, denying service to clients.
CVE-2020-9490 7 Apache, Canonical, Debian and 4 more 25 Http Server, Ubuntu Linux, Debian Linux and 22 more 2022-10-07 5.0 MEDIUM 7.5 HIGH
Apache HTTP Server versions 2.4.20 to 2.4.43. A specially crafted value for the 'Cache-Digest' header in a HTTP/2 request would result in a crash when the server actually tries to HTTP/2 PUSH a resource afterwards. Configuring the HTTP/2 feature via "H2Push off" will mitigate this vulnerability for unpatched servers.
CVE-2020-9274 4 Canonical, Debian, Fedoraproject and 1 more 5 Ubuntu Linux, Debian Linux, Extra Packages For Enterprise Linux and 2 more 2022-10-07 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Pure-FTPd 1.0.49. An uninitialized pointer vulnerability has been detected in the diraliases linked list. When the *lookup_alias(const char alias) or print_aliases(void) function is called, they fail to correctly detect the end of the linked list and try to access a non-existent list member. This is related to init_aliases in diraliases.c.
CVE-2019-9718 3 Canonical, Debian, Ffmpeg 3 Ubuntu Linux, Debian Linux, Ffmpeg 2022-10-06 4.3 MEDIUM 6.5 MEDIUM
In FFmpeg 3.2 and 4.1, a denial of service in the subtitle decoder allows attackers to hog the CPU via a crafted video file in Matroska format, because ff_htmlmarkup_to_ass in libavcodec/htmlsubtitles.c has a complex format argument to sscanf.
CVE-2018-15822 3 Canonical, Debian, Ffmpeg 3 Ubuntu Linux, Debian Linux, Ffmpeg 2022-10-06 5.0 MEDIUM 7.5 HIGH
The flv_write_packet function in libavformat/flvenc.c in FFmpeg through 2.8 does not check for an empty audio packet, leading to an assertion failure.
CVE-2018-16877 6 Canonical, Clusterlabs, Debian and 3 more 9 Ubuntu Linux, Pacemaker, Debian Linux and 6 more 2022-10-06 4.6 MEDIUM 7.8 HIGH
A flaw was found in the way pacemaker's client-server authentication was implemented in versions up to and including 2.0.0. A local attacker could use this flaw, and combine it with other IPC weaknesses, to achieve local privilege escalation.
CVE-2018-16878 6 Canonical, Clusterlabs, Debian and 3 more 9 Ubuntu Linux, Pacemaker, Debian Linux and 6 more 2022-10-06 2.1 LOW 5.5 MEDIUM
A flaw was found in pacemaker up to and including version 2.0.1. An insufficient verification inflicted preference of uncontrolled processes can lead to DoS
CVE-2018-13099 4 Canonical, Debian, Linux and 1 more 4 Ubuntu Linux, Debian Linux, Linux Kernel and 1 more 2022-10-06 4.3 MEDIUM 5.5 MEDIUM
An issue was discovered in fs/f2fs/inline.c in the Linux kernel through 4.4. A denial of service (out-of-bounds memory access and BUG) can occur for a modified f2fs filesystem image in which an inline inode contains an invalid reserved blkaddr.
