SB2012072517 - Input validation error in gperftools

Description

This security bulletin contains information about 1 vulnerability.

1) Input validation error (CVE-ID: CVE-2005-4895)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

Multiple integer overflows in TCMalloc (tcmalloc.cc) in gperftools before 0.4 make it easier for context-dependent attackers to perform memory-related attacks such as buffer overflows via a large size value, which causes less memory to be allocated than expected.

Remediation

Install update from vendor's website.
