CVE-2019-17020 2 Canonical, Mozilla 2 Ubuntu Linux, Firefox 2021-07-21 4.3 MEDIUM 6.5 MEDIUM
If an XML file is served with a Content Security Policy and the XML file includes an XSL stylesheet, the Content Security Policy will not be applied to the contents of the XSL stylesheet. If the XSL sheet e.g. includes JavaScript, it would bypass any of the restrictions of the Content Security Policy applied to the XML document. This vulnerability affects Firefox < 72.
CVE-2019-15031 4 Canonical, Linux, Opensuse and 1 more 4 Ubuntu Linux, Linux Kernel, Leap and 1 more 2021-07-21 3.6 LOW 4.4 MEDIUM
In the Linux kernel through 5.2.14 on the powerpc platform, a local user can read vector registers of other users' processes via an interrupt. To exploit the venerability, a local user starts a transaction (via the hardware transactional memory instruction tbegin) and then accesses vector registers. At some point, the vector registers will be corrupted with the values from a different local Linux process, because MSR_TM_ACTIVE is misused in arch/powerpc/kernel/process.c.
CVE-2019-19956 7 Canonical, Debian, Fedoraproject and 4 more 12 Ubuntu Linux, Debian Linux, Fedora and 9 more 2021-07-21 5.0 MEDIUM 7.5 HIGH
xmlParseBalancedChunkMemoryRecover in parser.c in libxml2 before 2.9.10 has a memory leak related to newDoc->oldNs.
CVE-2019-17542 3 Canonical, Debian, Ffmpeg 3 Ubuntu Linux, Debian Linux, Ffmpeg 2021-07-21 7.5 HIGH 9.8 CRITICAL
FFmpeg before 4.2 has a heap-based buffer overflow in vqa_decode_chunk because of an out-of-array access in vqa_decode_init in libavcodec/vqavideo.c.
CVE-2019-3463 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2021-07-21 7.5 HIGH 9.8 CRITICAL
Insufficient sanitization of arguments passed to rsync can bypass the restrictions imposed by rssh, a restricted shell that should restrict users to perform only rsync operations, resulting in the execution of arbitrary shell commands.
CVE-2019-14615 2 Canonical, Intel 709 Ubuntu Linux, Atom E3805, Atom E3805 Firmware and 706 more 2021-07-21 1.9 LOW 5.5 MEDIUM
Insufficient control flow in certain data structures for some Intel(R) Processors with Intel(R) Processor Graphics may allow an unauthenticated user to potentially enable information disclosure via local access.
CVE-2020-24606 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2021-07-21 7.1 HIGH 7.5 HIGH
Squid before 4.13 and 5.x before 5.0.4 allows a trusted peer to perform Denial of Service by consuming all available CPU cycles during handling of a crafted Cache Digest response message. This only occurs when cache_peer is used with the cache digests feature. The problem exists because peerDigestHandleReply() livelocking in peer_digest.cc mishandles EOF.
CVE-2020-5973 2 Canonical, Nvidia 2 Ubuntu Linux, Virtual Gpu 2021-07-21 2.1 LOW 4.4 MEDIUM
NVIDIA Virtual GPU Manager and the guest drivers contain a vulnerability in vGPU plugin, in which there is the potential to execute privileged operations, which may lead to denial of service. This affects vGPU version 8.x (prior to 8.4), version 9.x (prior to 9.4) and version 10.x (prior to 10.3).
CVE-2020-11501 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2021-07-21 5.8 MEDIUM 7.4 HIGH
GnuTLS 3.6.x before 3.6.13 uses incorrect cryptography for DTLS. The earliest affected version is 3.6.3 (2018-07-16) because of an error in a 2017-10-06 commit. The DTLS client always uses 32 '\0' bytes instead of a random value, and thus contributes no randomness to a DTLS negotiation. This breaks the security guarantees of the DTLS protocol.
CVE-2020-5963 2 Canonical, Nvidia 9 Ubuntu Linux, Geforce, Geforce Firmware and 6 more 2021-07-21 4.6 MEDIUM 7.8 HIGH
NVIDIA Windows GPU Display Driver, all versions, contains a vulnerability in the Inter Process Communication APIs, in which improper access control may lead to code execution, denial of service, or information disclosure.
CVE-2020-6514 6 Apple, Canonical, Debian and 3 more 11 Ipados, Iphone Os, Safari and 8 more 2021-07-21 4.3 MEDIUM 6.5 MEDIUM
Inappropriate implementation in WebRTC in Google Chrome prior to 84.0.4147.89 allowed an attacker in a privileged network position to potentially exploit heap corruption via a crafted SCTP stream.
CVE-2020-2604 7 Canonical, Debian, Mcafee and 4 more 25 Ubuntu Linux, Debian Linux, Epolicy Orchestrator and 22 more 2021-07-21 6.8 MEDIUM 8.1 HIGH
Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Serialization). Supported versions that are affected are Java SE: 7u241, 8u231, 11.0.5 and 13.0.1; Java SE Embedded: 8u231. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded. Successful attacks of this vulnerability can result in takeover of Java SE, Java SE Embedded. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets (in Java SE 8), that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability can also be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. CVSS v3.0 Base Score 8.1 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H).
CVE-2019-13627 4 Canonical, Debian, Libgcrypt20 Project and 1 more 4 Ubuntu Linux, Debian Linux, Libgcrypt20 and 1 more 2021-07-21 2.6 LOW 6.3 MEDIUM
It was discovered that there was a ECDSA timing attack in the libgcrypt20 cryptographic library. Version affected: 1.8.4-5, 1.7.6-2+deb9u3, and 1.6.3-2+deb8u4. Versions fixed: 1.8.5-2 and 1.6.3-2+deb8u7.
CVE-2019-3498 4 Canonical, Debian, Djangoproject and 1 more 4 Ubuntu Linux, Debian Linux, Django and 1 more 2021-07-21 4.3 MEDIUM 6.5 MEDIUM
In Django 1.11.x before 1.11.18, 2.0.x before 2.0.10, and 2.1.x before 2.1.5, an Improper Neutralization of Special Elements in Output Used by a Downstream Component issue exists in django.views.defaults.page_not_found(), leading to content spoofing (in a 404 error page) if a user fails to recognize that a crafted URL has malicious content.
CVE-2020-8517 3 Canonical, Opensuse, Squid-cache 3 Ubuntu Linux, Leap, Squid 2021-07-21 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Squid before 4.10. Due to incorrect input validation, the NTLM authentication credentials parser in ext_lm_group_acl may write to memory outside the credentials buffer. On systems with memory access protections, this can result in the helper process being terminated unexpectedly. This leads to the Squid process also terminating and a denial of service for all clients using the proxy.
CVE-2019-12521 4 Canonical, Debian, Opensuse and 1 more 4 Ubuntu Linux, Debian Linux, Leap and 1 more 2021-07-21 4.3 MEDIUM 5.9 MEDIUM
An issue was discovered in Squid through 4.7. When Squid is parsing ESI, it keeps the ESI elements in ESIContext. ESIContext contains a buffer for holding a stack of ESIElements. When a new ESIElement is parsed, it is added via addStackElement. addStackElement has a check for the number of elements in this buffer, but it's off by 1, leading to a Heap Overflow of 1 element. The overflow is within the same structure so it can't affect adjacent memory blocks, and thus just leads to a crash while processing.
CVE-2019-11815 5 Canonical, Debian, Linux and 2 more 15 Ubuntu Linux, Debian Linux, Linux Kernel and 12 more 2021-07-21 9.3 HIGH 8.1 HIGH
An issue was discovered in rds_tcp_kill_sock in net/rds/tcp.c in the Linux kernel before 5.0.8. There is a race condition leading to a use-after-free, related to net namespace cleanup.
CVE-2019-7306 2 Byobu, Canonical 2 Byobu, Ubuntu Linux 2021-07-21 5.0 MEDIUM 7.5 HIGH
Byobu Apport hook may disclose sensitive information since it automatically uploads the local user's .screenrc which may contain private hostnames, usernames and passwords. This issue affects: byobu
CVE-2020-11996 6 Apache, Canonical, Debian and 3 more 8 Tomcat, Ubuntu Linux, Debian Linux and 5 more 2021-07-21 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-2020-12662 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2021-07-21 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.
