Detailsinfo

A vulnerability was found in Linux Kernel 2.4.34 (Operating System). It has been declared as critical. Affected by this vulnerability is the function xfer_secondary_pool of the component Random Number Generator. The manipulation with an unknown input leads to a cryptographic issue vulnerability. The CWE definition for the vulnerability is CWE-310. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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.

The weakness was presented 08/13/2007 (Website). The advisory is shared at vupen.com. This vulnerability is known as CVE-2007-4311 since 08/13/2007. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1600 for this issue.

It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 31147 (Debian DSA-1503-1 : kernel-source-2.4.27 - several vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks.

Upgrading to version 2.4.34 eliminates this vulnerability.

The vulnerability is also documented in the databases at X-Force (36077), Tenable (31147), SecurityFocus (BID 25029†), Secunia (SA29058†) and Vulnerability Center (SBV-23008†).
