CVE-2013-4345
Last modified
CVE-2013-4345 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 3.18% chance of exploitation in the next 30 days.
