CVE-2013-4345

Priority
Description
Off-by-one error in the get_prng_bytes function in crypto/ansi_cprng.c in
the Linux kernel through 3.11.4 makes it easier for context-dependent
attackers to defeat cryptographic protection mechanisms via multiple
requests for small amounts of data, leading to improper management of the
state of the consumed data.
Ubuntu-Description
Stephan Mueller reported an error in the Linux kernel's ansi cprng random
number generator. This flaw makes it easier for a local attacker to break
cryptographic protections.
