Debian DSA-2949-1 : linux - security update
High Nessus Plugin ID 74336
Synopsis
The remote Debian host is missing a security-related update.
Description
Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or privilege escalation :
- CVE-2014-3144/ CVE-2014-3145 A local user can cause a denial of service (system crash) via crafted BPF instructions.
- CVE-2014-3153 Pinkie Pie discovered an issue in the futex subsystem that allows a local user to gain ring 0 control via the futex syscall. An unprivileged user could use this flaw to crash the kernel (resulting in denial of service) or for privilege escalation.
Solution
Upgrade the linux packages.
For the stable distribution (wheezy), these problems have been fixed in version 3.2.57-3+deb7u2.
