Detailsinfo

A vulnerability was found in GNU tar 1.14/1.14.1/1.15/1.15.1/1.15.90. It has been rated as critical. Affected by this issue is some unknown functionality of the component PAX Header Handler. 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:

Buffer overflow in tar 1.14 through 1.15.90 allows user-assisted attackers to cause a denial of service (application crash) and possibly execute code via unspecified vectors involving PAX extended headers.

The bug was discovered 02/22/2006. The weakness was published 02/22/2006 by Jim Meyering with Entwickler-Team (Website). The advisory is shared for download at lists.gnu.org. This vulnerability is handled as CVE-2006-0300 since 01/18/2006. The attack can only be initiated within the local network. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available.
