CVE-2020-12406 2 Canonical, Mozilla 4 Ubuntu Linux, Firefox, Firefox Esr and 1 more 2024-11-21 9.3 HIGH 8.8 HIGH
Mozilla Developer Iain Ireland discovered a missing type check during unboxed objects removal, resulting in a crash. We presume that with enough effort that it could be exploited to run arbitrary code. This vulnerability affects Thunderbird < 68.9.0, Firefox < 77, and Firefox ESR < 68.9.
CVE-2020-12405 2 Canonical, Mozilla 4 Ubuntu Linux, Firefox, Firefox Esr and 1 more 2024-11-21 2.6 LOW 5.3 MEDIUM
When browsing a malicious page, a race condition in our SharedWorkerService could occur and lead to a potentially exploitable crash. This vulnerability affects Thunderbird < 68.9.0, Firefox < 77, and Firefox ESR < 68.9.
CVE-2020-12398 2 Canonical, Mozilla 2 Ubuntu Linux, Thunderbird 2024-11-21 4.3 MEDIUM 7.5 HIGH
If Thunderbird is configured to use STARTTLS for an IMAP server, and the server sends a PREAUTH response, then Thunderbird will continue with an unencrypted connection, causing email data to be sent without protection. This vulnerability affects Thunderbird < 68.9.0.
CVE-2020-12397 2 Canonical, Mozilla 2 Ubuntu Linux, Thunderbird 2024-11-21 4.3 MEDIUM 4.3 MEDIUM
By encoding Unicode whitespace characters within the From email header, an attacker can spoof the sender email address that Thunderbird displays. This vulnerability affects Thunderbird < 68.8.0.
CVE-2020-12395 2 Canonical, Mozilla 4 Ubuntu Linux, Firefox, Firefox Esr and 1 more 2024-11-21 10.0 HIGH 9.8 CRITICAL
Mozilla developers and community members reported memory safety bugs present in Firefox 75 and Firefox ESR 68.7. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox ESR < 68.8, Firefox < 76, and Thunderbird < 68.8.0.
CVE-2020-12392 2 Canonical, Mozilla 4 Ubuntu Linux, Firefox, Firefox Esr and 1 more 2024-11-21 2.1 LOW 5.5 MEDIUM
The 'Copy as cURL' feature of Devtools' network tab did not properly escape the HTTP POST data of a request, which can be controlled by the website. If a user used the 'Copy as cURL' feature and pasted the command into a terminal, it could have resulted in the disclosure of local files. This vulnerability affects Firefox ESR < 68.8, Firefox < 76, and Thunderbird < 68.8.0.
CVE-2020-12284 3 Canonical, Debian, Ffmpeg 3 Ubuntu Linux, Debian Linux, Ffmpeg 2024-11-21 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-2020-12243 8 Apple, Broadcom, Canonical and 5 more 26 Mac Os X, Brocade Fabric Operating System, Ubuntu Linux and 23 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
In filter.c in slapd in OpenLDAP before 2.4.50, LDAP search filters with nested boolean expressions can result in denial of service (daemon crash).
CVE-2020-12137 5 Canonical, Debian, Fedoraproject and 2 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2024-11-21 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 2024-11-21 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 2024-11-21 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 2024-11-21 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-2020-12059 2 Canonical, Linuxfoundation 2 Ubuntu Linux, Ceph 2024-11-21 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Ceph through 13.2.9. A POST request with an invalid tagging XML can crash the RGW process by triggering a NULL pointer exception.
CVE-2020-12049 2 Canonical, Freedesktop 2 Ubuntu Linux, Dbus 2024-11-21 4.9 MEDIUM 5.5 MEDIUM
An issue was discovered in dbus >= 1.3.0 before 1.12.18. The DBusServer in libdbus, as used in dbus-daemon, leaks file descriptors when a message exceeds the per-message file descriptor limit. A local attacker with access to the D-Bus system bus or another system service's private AF_UNIX socket could use this to make the system service reach its file descriptor limit, denying service to subsequent D-Bus clients.
CVE-2020-11996 6 Apache, Canonical, Debian and 3 more 8 Tomcat, Ubuntu Linux, Debian Linux and 5 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
A specially crafted sequence of HTTP/2 requests sent to Apache Tomcat 10.0.0-M1 to 10.0.0-M5, 9.0.0.M1 to 9.0.35 and 8.5.0 to 8.5.55 could trigger high CPU usage for several seconds. If a sufficient number of such requests were made on concurrent HTTP/2 connections, the server could become unresponsive.
CVE-2020-11984 7 Apache, Canonical, Debian and 4 more 13 Http Server, Ubuntu Linux, Debian Linux and 10 more 2024-11-21 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-2020-11958 2 Canonical, Re2c 2 Ubuntu Linux, Re2c 2024-11-21 6.8 MEDIUM 7.8 HIGH
re2c 1.3 has a heap-based buffer overflow in Scanner::fill in parse/scanner.cc via a long lexeme.
CVE-2020-11945 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2024-11-21 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-2020-11937 1 Canonical 2 Ubuntu Linux, Whoopsie 2024-11-21 2.1 LOW 5.5 MEDIUM
In whoopsie, parse_report() from whoopsie.c allows a local attacker to cause a denial of service via a crafted file. The DoS is caused by resource exhaustion due to a memory leak. Fixed in 0.2.52.5ubuntu0.5, 0.2.62ubuntu0.5 and 0.2.69ubuntu0.1.
CVE-2020-11935 2 Canonical, Debian 2 Ubuntu Linux, Debian Linux 2024-11-21 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.
