The ext4_fill_super function in fs/ext4/super.c in the Linux kernel through 4.15.15 does not always initialize the crc32c checksum driver, which allows attackers to cause a denial of service (ext4_xattr_inode_hash NULL pointer dereference and system crash) via a crafted ext4 image.
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.

In coders/psd.c in ImageMagick 7.0.7-0 Q16, a DoS in ReadPSDLayersInternal() due to lack of an EOF (End of File) check might cause huge CPU consumption. When a crafted PSD file, which claims a large "length" field in the header but does not contain sufficient backing data, is provided, the loop over "length" would consume huge CPU resources, since there is no EOF check inside the loop.
CVE-2014-1483 5 Canonical, Mozilla, Opensuse and 2 more 8 Ubuntu Linux, Firefox, Seamonkey and 5 more 2020-10-23 5.0 MEDIUM N/A
