CVE-2013-7421

The Crypto API in the Linux kernel before 3.18.5 allows local users to load arbitrary kernel modules via a bind system call for an AF_ALG socket with a module name in the salg_name field, a different vulnerability than CVE-2014-9644.

USN-2544-1 — linux vulnerabilities

Affected: Ubuntu:14.04:LTS: linux

Eric Windisch discovered flaw in how the Linux kernel's XFS file system replaces remote attributes. A local access with access to an XFS file system could exploit this flaw to escalate their privileges. (CVE-2015-0274)

A flaw was discovered in the automatic loading of modules in the crypto subsystem of the Linux kernel. A local user could exploit this flaw to load installed kernel modules, increasing the attack surface and potentially using this to gain administrative privileges. (CVE-2013-7421)

The Linux kernel's splice system call did not correctly validate its parameters. A local, unprivileged user could exploit this flaw to cause a denial of service (system crash). (CVE-2014-7822)

A flaw was discovered in the crypto subsystem when screening module names for automatic module loading if the name contained a valid crypto module name, eg. vfat(aes). A local user could exploit this flaw to load installed kernel modules, increasing the attack surface and potentially using this to gain administrative privileges. (CVE-2014-9644)

Carl H Lunde discovered that the UDF file system (CONFIG_UDF_FS) failed to verify symlink size info. A local attacker, who is able to mount a malicous UDF file system image, could exploit this flaw to cause a denial of service (system crash) or possibly cause other undesired behaviors. (CVE-2014-9728)

Carl H Lunde discovered that the UDF file system (CONFIG_UDF_FS) did not valid inode size information . A local attacker, who is able to mount a malic…
