Detailsinfo

A vulnerability was found in IBM AIX 5.1/5.2/5.3 (Operating System). It has been classified as critical. This affects some unknown functionality. The manipulation of the argument -O with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as 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. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Buffer overflow in netpmon on AIX 5.1, 5.2, and 5.3 allows local users to execute arbitrary code via a long -O argument.

The issue has been introduced in 05/01/2001. The weakness was shared 02/10/2005 by iDefense Labs with iDEFENSE Labs (Website). The advisory is shared at idefense.com. This vulnerability is uniquely identified as CVE-2005-0263 since 02/10/2005. The exploitability is told to be easy. An attack has to be approached locally. No form of authentication is needed for exploitation. Technical details and a public exploit are known.

After 5 months, there has been an exploit disclosed. The exploit is shared for download at securiteam.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 1381 days. During that time the estimated underground price was around $25k-$100k.

Upgrading to version 6.1 eliminates this vulnerability. A possible mitigation has been published 2 months after the disclosure of the vulnerability.
