A vulnerability classified as problematic has been found in Khaled Mardam-Bey mIRC 5.91/6.03/6.12/6.16 (Chat Software). This affects some unknown processing. The manipulation 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:

** DISPUTED ** Buffer overflow in mIRC 5.91, 6.03, 6.12, and 6.16 allows local users to execute arbitrary code via a long string that is entered after reaching the DCC Get Folder Dialog. NOTE: this issue has been disputed by the vendor, saying "as far as I can tell, this is neither an exploit nor a vulnerability. The above report describes a local bug in mIRC." It could be that this is only exploitable by the user of the application, and thus would not cross privilege boundaries unless under an otherwise restrictive environment such as a kiosk.

The bug was discovered 11/29/2005. The weakness was shared 12/09/2005 by Jordi Corrales (Website). It is possible to read the advisory at shellsec.net. This vulnerability is uniquely identified as CVE-2005-4681 since 01/31/2006. The exploitability is told to be easy. Attacking locally is a requirement. No form of authentication is needed for exploitation. Technical details are unknown but an exploit is available.

After even before and not, 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 10 days. During that time the estimated underground price was around $0-$5k. The real existence of this vulnerability is still doubted at the moment.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
