Amazon Linux AMI Security Advisory: ALAS-2012-83
Advisory Release Date: 2012-06-10 11:46 Pacific
Advisory Updated Date: 2014-09-14 16:13 Pacific
Severity:
Medium
Issue Overview:
It was found that the data_len parameter of the sock_alloc_send_pskb() function in the Linux kernel's networking implementation was not validated before use. A local user with access to a TUN/TAP virtual interface could use this flaw to crash the system or, potentially, escalate their privileges. Note that unprivileged users cannot access TUN/TAP devices until the root user grants them access. (CVE-2012-2136, Important)
