Description GLSAMaker/CVETool Bot gentoo-dev 2014-01-11 17:59:44 UTC 
CVE-2013-7271 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-7271):
  The x25_recvmsg function in net/x25/af_x25.c in the Linux kernel before
  3.12.4 updates a certain length value without ensuring that an associated
  data structure has been initialized, which allows local users to obtain
  sensitive information from kernel memory via a (1) recvfrom, (2) recvmmsg,
  or (3) recvmsg system call.
