Description GLSAMaker/CVETool Bot gentoo-dev 2014-01-12 04:05:43 UTC 
CVE-2013-7270 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-7270):
  The packet_recvmsg function in net/packet/af_packet.c in the Linux kernel
  before 3.12.4 updates a certain length value before 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.
