Описание
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.
Отчет
This issue affects the versions of Linux kernel as shipped with Red Hat Enterprise Linux 5, 6 and Red Hat Enterprise MRG 2. Future kernel updates for Red Hat Enterprise Linux 5, 6 and Red Hat Enterprise MRG 2 may address this issue.
