CVE-2020-13631 8 Apple, Brocade, Canonical and 5 more 19 Icloud, Ipados, Iphone Os and 16 more 2023-11-07 2.1 LOW 5.5 MEDIUM
SQLite before 3.32.0 allows a virtual table to be renamed to the name of one of its shadow tables, related to alter.c and build.c.
CVE-2020-13625 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
PHPMailer before 6.1.6 contains an output escaping bug when the name of a file attachment contains a double quote character. This can result in the file type being misinterpreted by the receiver or any mail relay processing the message.
CVE-2020-13904 3 Canonical, Debian, Ffmpeg 3 Ubuntu Linux, Debian Linux, Ffmpeg 2023-11-07 4.3 MEDIUM 5.5 MEDIUM
FFmpeg 2.8 and 4.2.3 has a use-after-free via a crafted EXTINF duration in an m3u8 file because parse_playlist in libavformat/hls.c frees a pointer, and later that pointer is accessed in av_probe_input_format3 in libavformat/format.c.
CVE-2020-13753 6 Canonical, Debian, Fedoraproject and 3 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2023-11-07 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-2020-13645 5 Broadcom, Canonical, Fedoraproject and 2 more 6 Fabric Operating System, Ubuntu Linux, Fedora and 3 more 2023-11-07 6.4 MEDIUM 6.5 MEDIUM
In GNOME glib-networking through 2.64.2, the implementation of GTlsClientConnection skips hostname verification of the server's TLS certificate if the application fails to specify the expected server identity. This is in contrast to its intended documented behavior, to fail the certificate verification. Applications that fail to provide the server identity, including Balsa before 2.5.11 and 2.6.x before 2.6.1, accept a TLS certificate if the certificate is valid for any host.
CVE-2020-13596 6 Canonical, Debian, Djangoproject and 3 more 7 Ubuntu Linux, Debian Linux, Django and 4 more 2023-11-07 4.3 MEDIUM 6.1 MEDIUM
An issue was discovered in Django 2.2 before 2.2.13 and 3.0 before 3.0.7. Query parameters generated by the Django admin ForeignKeyRawIdWidget were not properly URL encoded, leading to a possibility of an XSS attack.
CVE-2020-13254 6 Canonical, Debian, Djangoproject and 3 more 7 Ubuntu Linux, Debian Linux, Django and 4 more 2023-11-07 4.3 MEDIUM 5.9 MEDIUM
An issue was discovered in Django 2.2 before 2.2.13 and 3.0 before 3.0.7. In cases where a memcached backend does not perform key validation, passing malformed cache keys could result in a key collision, and potential data leakage.
CVE-2020-13757 3 Canonical, Fedoraproject, Python-rsa Project 3 Ubuntu Linux, Fedora, Python-rsa 2023-11-07 5.0 MEDIUM 7.5 HIGH
Python-RSA before 4.1 ignores leading '\0' bytes during decryption of ciphertext. This could conceivably have a security-relevant impact, e.g., by helping an attacker to infer that an application uses Python-RSA, or if the length of accepted ciphertext affects application behavior (such as by causing excessive memory allocation).
CVE-2020-12673 4 Canonical, Debian, Dovecot and 1 more 4 Ubuntu Linux, Debian Linux, Dovecot and 1 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
In Dovecot before 2.3.11.3, sending a specially formatted NTLM request will crash the auth service because of an out-of-bounds read.
CVE-2020-12108 5 Canonical, Debian, Fedoraproject and 2 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2023-11-07 4.3 MEDIUM 6.5 MEDIUM
/options/mailman in GNU Mailman before 2.1.31 allows Arbitrary Content Injection.
CVE-2020-12662 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
Unbound before 1.10.1 has Insufficient Control of Network Message Volume, aka an "NXNSAttack" issue. This is triggered by random subdomains in the NSDNAME in NS records.
CVE-2020-11884 5 Canonical, Debian, Fedoraproject and 2 more 35 Ubuntu Linux, Debian Linux, Fedora and 32 more 2023-11-07 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-2020-12691 2 Canonical, Openstack 2 Ubuntu Linux, Keystone 2023-11-07 6.5 MEDIUM 8.8 HIGH
An issue was discovered in OpenStack Keystone before 15.0.1, and 16.0.0. Any authenticated user can create an EC2 credential for themselves for a project that they have a specified role on, and then perform an update to the credential user and project, allowing them to masquerade as another user. This potentially allows a malicious user to act as the admin on a project another user has the admin role on, which can effectively grant that user global admin privileges.
CVE-2020-12867 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2023-11-07 2.1 LOW 5.5 MEDIUM
A NULL pointer dereference in sanei_epson_net_read in SANE Backends before 1.0.30 allows a malicious device connected to the same local network as the victim to cause a denial of service, aka GHSL-2020-075.
CVE-2020-11760 6 Apple, Canonical, Debian and 3 more 12 Icloud, Ipados, Iphone Os and 9 more 2023-11-07 4.3 MEDIUM 5.5 MEDIUM
An issue was discovered in OpenEXR before 2.4.1. There is an out-of-bounds read during RLE uncompression in rleUncompress in ImfRle.cpp.
CVE-2020-12674 4 Canonical, Debian, Dovecot and 1 more 4 Ubuntu Linux, Debian Linux, Dovecot and 1 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
In Dovecot before 2.3.11.3, sending a specially formatted RPA request will crash the auth service because a length of zero is mishandled.
CVE-2020-11764 6 Apple, Canonical, Debian and 3 more 12 Icloud, Ipados, Iphone Os and 9 more 2023-11-07 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-2020-12137 5 Canonical, Debian, Fedoraproject and 2 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2023-11-07 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-2020-12066 5 Canonical, Debian, Fedoraproject and 2 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2023-11-07 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-2020-11945 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2023-11-07 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).
