CVE-2019-3821 2 Canonical, Ceph 2 Ubuntu Linux, Civetweb 2020-11-13 5.0 MEDIUM 7.5 HIGH
A flaw was found in the way civetweb frontend was handling requests for ceph RGW server with SSL enabled. An unauthenticated attacker could create multiple connections to ceph RADOS gateway to exhaust file descriptors for ceph-radosgw service resulting in a remote denial of service.
CVE-2020-15708 1 Canonical 1 Ubuntu Linux 2020-11-12 4.6 MEDIUM 7.8 HIGH
Ubuntu's packaging of libvirt in 20.04 LTS created a control socket with world read and write permissions. An attacker could use this to overwrite arbitrary files or execute arbitrary code.
CVE-2018-5802 4 Canonical, Debian, Libraw and 1 more 6 Ubuntu Linux, Debian Linux, Libraw and 3 more 2020-11-10 6.8 MEDIUM 8.8 HIGH
An error within the "kodak_radc_load_raw()" function (internal/dcraw_common.cpp) related to the "buf" variable in LibRaw versions prior to 0.18.7 can be exploited to cause an out-of-bounds read memory access and subsequently cause a crash.
CVE-2019-19959 2 Canonical, Sqlite 2 Ubuntu Linux, Sqlite 2020-11-09 5.0 MEDIUM 7.5 HIGH
ext/misc/zipfile.c in SQLite 3.30.1 mishandles certain uses of INSERT INTO in situations involving embedded '\0' characters in filenames, leading to a memory-management error that can be detected by (for example) valgrind.
CVE-2020-13398 4 Canonical, Debian, Freerdp and 1 more 4 Ubuntu Linux, Debian Linux, Freerdp and 1 more 2020-11-09 6.5 MEDIUM 8.3 HIGH
An issue was discovered in FreeRDP before 2.1.1. An out-of-bounds (OOB) write vulnerability has been detected in crypto_rsa_common in libfreerdp/crypto/crypto.c.
CVE-2017-18509 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2020-11-09 7.2 HIGH 7.8 HIGH
An issue was discovered in net/ipv6/ip6mr.c in the Linux kernel before 4.11. By setting a specific socket option, an attacker can control a pointer in kernel land and cause an inet_csk_listen_stop general protection fault, or potentially execute arbitrary code under certain circumstances. The issue can be triggered as root (e.g., inside a default LXC container or with the CAP_NET_ADMIN capability) or after namespace unsharing. This occurs because sk_type and protocol are not checked in the appropriate part of the ip6_mroute_* functions. NOTE: this affects Linux distributions that use 4.9.x longterm kernels before 4.9.187.

The ReadWPGImage function in coders/wpg.c in ImageMagick 7.0.7-9 does not properly validate the colormap index in a WPG palette, which allows remote attackers to cause a denial of service (use of uninitialized data or invalid memory allocation) or possibly have unspecified other impact via a malformed WPG file.
CVE-2019-9515 11 Apache, Apple, Canonical and 8 more 23 Traffic Server, Mac Os X, Swiftnio and 20 more 2020-10-22 7.8 HIGH 7.5 HIGH
Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of service. The attacker sends a stream of SETTINGS frames to the peer. Since the RFC requires that the peer reply with one acknowledgement per SETTINGS frame, an empty SETTINGS frame is almost equivalent in behavior to a ping. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.
CVE-2018-10583 5 Apache, Canonical, Debian and 2 more 7 Openoffice, Ubuntu Linux, Debian Linux and 4 more 2020-10-21 5.0 MEDIUM 7.5 HIGH

A vulnerability in the seccomp filters of Canonical snapd before version 2.37.4 allows a strict mode snap to insert characters into a terminal on a 64-bit host. The seccomp rules were generated to match 64-bit ioctl(2) commands on a 64-bit platform; however, the Linux kernel only uses the lower 32 bits to determine which ioctl(2) commands to run. This issue affects: Canonical snapd versions prior to 2.37.4.
