Detailsinfo

A vulnerability classified as critical has been found in GNU Openswan up to 1.0.9/2.3.0. This affects some unknown processing of the component XAUTH/PAM. The manipulation with an unknown input leads to a stack-based overflow vulnerability. CWE is classifying the issue as CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Stack-based buffer overflow in the get_internal_addresses function in the pluto application for Openswan 1.x before 1.0.9, and Openswan 2.x before 2.3.0, when compiled with XAUTH and PAM enabled, allows remote authenticated attackers to execute arbitrary code.

The weakness was released 01/26/2005 with iDEFENSE (Website). The advisory is shared at idefense.com. This vulnerability is uniquely identified as CVE-2005-0162 since 01/27/2005.
