CVE-2007-4311
Linux Kernel Random Number Generator Predictable Resource Consumption Vulnerability
Description

The xfer_secondary_pool function in drivers/char/random.c in the Linux kernel 2.4 before 2.4.35 performs reseed operations on only the first few bytes of a buffer, which might make it easier for attackers to predict the output of the random number generator, related to incorrect use of the sizeof operator.
