CVE-2020-12284 3 Canonical, Debian, Ffmpeg 3 Ubuntu Linux, Debian Linux, Ffmpeg 2026-06-17 10.0 HIGH 9.8 CRITICAL
cbs_jpeg_split_fragment in libavcodec/cbs_jpeg.c in FFmpeg 4.1 and 4.2.2 has a heap-based buffer overflow during JPEG_MARKER_SOS handling because of a missing length check.
CVE-2020-12279 2 Debian, Libgit2 2 Debian Linux, Libgit2 2026-06-17 7.5 HIGH 9.8 CRITICAL
An issue was discovered in libgit2 before 0.28.4 and 0.9x before 0.99.0. checkout.c mishandles equivalent filenames that exist because of NTFS short names. This may allow remote code execution when cloning a repository. This issue is similar to CVE-2019-1353.
CVE-2020-12278 2 Debian, Libgit2 2 Debian Linux, Libgit2 2026-06-17 7.5 HIGH 9.8 CRITICAL
An issue was discovered in libgit2 before 0.28.4 and 0.9x before 0.99.0. path.c mishandles equivalent filenames that exist because of NTFS Alternate Data Streams. This may allow remote code execution when cloning a repository. This issue is similar to CVE-2019-1352.
CVE-2020-12268 3 Artifex, Debian, Opensuse 3 Jbig2dec, Debian Linux, Leap 2026-06-17 7.5 HIGH 9.8 CRITICAL
jbig2_image_compose in jbig2_image.c in Artifex jbig2dec before 0.18 has a heap-based buffer overflow.
CVE-2020-12244 4 Debian, Fedoraproject, Opensuse and 1 more 5 Debian Linux, Fedora, Backports Sle and 2 more 2026-06-17 5.0 MEDIUM 7.5 HIGH
An issue has been found in PowerDNS Recursor 4.1.0 through 4.3.0 where records in the answer section of a NXDOMAIN response lacking an SOA were not properly validated in SyncRes::processAnswer, allowing an attacker to bypass DNSSEC validation.
CVE-2020-12137 5 Canonical, Debian, Fedoraproject and 2 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2026-06-17 4.3 MEDIUM 6.1 MEDIUM
GNU Mailman 2.x before 2.1.30 uses the .obj extension for scrubbed application/octet-stream MIME parts. This behavior may contribute to XSS attacks against list-archive visitors, because an HTTP reply from an archive web server may lack a MIME type, and a web browser may perform MIME sniffing, conclude that the MIME type should have been text/html, and execute JavaScript code.
CVE-2020-12108 5 Canonical, Debian, Fedoraproject and 2 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2026-06-17 4.3 MEDIUM 6.5 MEDIUM
/options/mailman in GNU Mailman before 2.1.31 allows Arbitrary Content Injection.
CVE-2020-12100 4 Canonical, Debian, Dovecot and 1 more 4 Ubuntu Linux, Debian Linux, Dovecot and 1 more 2026-06-17 5.0 MEDIUM 7.5 HIGH
In Dovecot before 2.3.11.3, uncontrolled recursion in submission, lmtp, and lda allows remote attackers to cause a denial of service (resource consumption) via a crafted e-mail message with deeply nested MIME parts.
CVE-2020-12066 5 Canonical, Debian, Fedoraproject and 2 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2026-06-17 7.8 HIGH 7.5 HIGH
CServer::SendMsg in engine/server/server.cpp in Teeworlds 0.7.x before 0.7.5 allows remote attackers to shut down the server.
CVE-2020-11993 7 Apache, Canonical, Debian and 4 more 13 Http Server, Ubuntu Linux, Debian Linux and 10 more 2026-06-17 4.3 MEDIUM 7.5 HIGH
Apache HTTP Server versions 2.4.20 to 2.4.43 When trace/debug was enabled for the HTTP/2 module and on certain traffic edge patterns, logging statements were made on the wrong connection, causing concurrent use of memory pools. Configuring the LogLevel of mod_http2 above "info" will mitigate this vulnerability for unpatched servers.
CVE-2020-11984 7 Apache, Canonical, Debian and 4 more 13 Http Server, Ubuntu Linux, Debian Linux and 10 more 2026-06-17 7.5 HIGH 9.8 CRITICAL
Apache HTTP server 2.4.32 to 2.4.44 mod_proxy_uwsgi info disclosure and possible RCE
CVE-2020-11945 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2026-06-17 7.5 HIGH 9.8 CRITICAL
An issue was discovered in Squid before 5.0.2. A remote attacker can replay a sniffed Digest Authentication nonce to gain access to resources that are otherwise forbidden. This occurs because the attacker can overflow the nonce reference counter (a short integer). Remote code execution may occur if the pooled token credentials are freed (instead of replayed as valid credentials).
CVE-2020-11935 2 Canonical, Debian 2 Ubuntu Linux, Debian Linux 2026-06-17 N/A 4.4 MEDIUM
It was discovered that aufs improperly managed inode reference counts in the vfsub_dentry_open() method. A local attacker could use this vulnerability to cause a denial of service attack.
CVE-2020-11884 5 Canonical, Debian, Fedoraproject and 2 more 35 Ubuntu Linux, Debian Linux, Fedora and 32 more 2026-06-17 6.9 MEDIUM 7.0 HIGH
In the Linux kernel 4.19 through 5.6.7 on the s390 platform, code execution may occur because of a race condition, as demonstrated by code in enable_sacf_uaccess in arch/s390/lib/uaccess.c that fails to protect against a concurrent page table upgrade, aka CID-3f777e19d171. A crash could also occur.
CVE-2020-11868 5 Debian, Netapp, Ntp and 2 more 24 Debian Linux, All Flash Fabric-attached Storage 8300, All Flash Fabric-attached Storage 8300 Firmware and 21 more 2026-06-17 5.0 MEDIUM 7.5 HIGH
ntpd in ntp before 4.2.8p14 and 4.3.x before 4.3.100 allows an off-path attacker to block unauthenticated synchronization via a server mode packet with a spoofed source IP address, because transmissions are rescheduled even when a packet lacks a valid origin timestamp.
CVE-2020-11810 3 Debian, Fedoraproject, Openvpn 3 Debian Linux, Fedora, Openvpn 2026-06-17 4.3 MEDIUM 3.7 LOW
An issue was discovered in OpenVPN 2.4.x before 2.4.9. An attacker can inject a data channel v2 (P_DATA_V2) packet using a victim's peer-id. Normally such packets are dropped, but if this packet arrives before the data channel crypto parameters have been initialized, the victim's connection will be dropped. This requires careful timing due to the small time window (usually within a few seconds) between the victim client connection starting and the server PUSH_REPLY response back to the client. This attack will only work if Negotiable Cipher Parameters (NCP) is in use.
CVE-2020-11800 3 Debian, Opensuse, Zabbix 4 Debian Linux, Backports Sle, Leap and 1 more 2026-06-17 7.5 HIGH 9.8 CRITICAL
Zabbix Server 2.2.x and 3.0.x before 3.0.31, and 3.2 allows remote attackers to execute arbitrary code.
CVE-2020-11765 6 Apple, Canonical, Debian and 3 more 12 Icloud, Ipados, Iphone Os and 9 more 2026-06-17 4.3 MEDIUM 5.5 MEDIUM
An issue was discovered in OpenEXR before 2.4.1. There is an off-by-one error in use of the ImfXdr.h read function by DwaCompressor::Classifier::Classifier, leading to an out-of-bounds read.
CVE-2020-11764 6 Apple, Canonical, Debian and 3 more 12 Icloud, Ipados, Iphone Os and 9 more 2026-06-17 4.3 MEDIUM 5.5 MEDIUM
An issue was discovered in OpenEXR before 2.4.1. There is an out-of-bounds write in copyIntoFrameBuffer in ImfMisc.cpp.
CVE-2020-11763 6 Apple, Canonical, Debian and 3 more 12 Icloud, Ipados, Iphone Os and 9 more 2026-06-17 4.3 MEDIUM 5.5 MEDIUM
An issue was discovered in OpenEXR before 2.4.1. There is an std::vector out-of-bounds read and write, as demonstrated by ImfTileOffsets.cpp.
