CVE-2020-12689 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 user authenticated within a limited scope (trust/oauth/application credential) can create an EC2 credential with an escalated permission, such as obtaining admin while the user is on a limited viewer role. 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-2020-12674 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-2020-12673 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-2020-12663 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 an infinite loop via malformed DNS answers received from upstream servers.
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-2020-12137 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-2020-12108 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-2020-12100 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, 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 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-2020-11996 6 Apache, Canonical, Debian and 3 more 8 Tomcat, Ubuntu Linux, Debian Linux and 5 more 2023-11-07 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-2020-11993 7 Apache, Canonical, Debian and 4 more 13 Http Server, Ubuntu Linux, Debian Linux and 10 more 2023-11-07 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 2023-11-07 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 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).
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-2020-11793 5 Canonical, Fedoraproject, Opensuse and 2 more 5 Ubuntu Linux, Fedora, Leap and 2 more 2023-11-07 6.8 MEDIUM 8.8 HIGH
A use-after-free issue exists in WebKitGTK before 2.28.1 and WPE WebKit before 2.28.1 via crafted web content that allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash).
CVE-2020-11765 6 Apple, Canonical, Debian and 3 more 12 Icloud, Ipados, Iphone Os and 9 more 2023-11-07 4.3 MEDIUM 5.5 MEDIUM
