[USN-2545-1] Linux kernel (Utopic HWE) vulnerabilities

Severity Medium
Affected Packages 8
CVEs 4
Info Packages Vulnerabilities

Several security issues were fixed in the kernel.

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)

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)

Sun Baoliang discovered a use after free flaw in the Linux kernel's SCTP
(Stream Control Transmission Protocol) subsystem during INIT collisions. A
remote attacker could exploit this flaw to cause a denial of service
(system crash) or potentially escalate their privileges on the system.
(CVE-2015-1421)

Marcelo Leitner discovered a flaw in the Linux kernel's routing of packets
to too many different dsts/too fast. A remote attacker can exploit this
flaw to cause a denial of service (system crash). (CVE-2015-1465)
