Detailsinfo

A vulnerability, which was classified as critical, has been found in Samba up to 3.5.4 (File Transfer Software). Affected by this issue is the function sid_parse of the component SID Parser. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Stack-based buffer overflow in the (1) sid_parse and (2) dom_sid_parse functions in Samba before 3.5.5 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted Windows Security ID (SID) on a file share.

The weakness was presented 09/14/2010 by Andrew Bartlett with Cisco (Website). The advisory is available at us1.samba.org. This vulnerability is handled as CVE-2010-3069 since 08/20/2010. The attack may be launched remotely. No form of authentication is required for exploitation. Technical details are known, but there is no available exploit.
