Description:
Secunia Research has discovered a vulnerability in AhnLab V3 Antivirus, which can be exploited by malicious people to compromise a vulnerable system.
The vulnerability is caused due to a boundary error in the archive decompression library when reading the filename of a compressed file from an ALZ, UUE or XXE archive. This can be exploited to cause a stack-based buffer overflow (ALZ), or a heap-based buffer overflow (UUE/XXE), when a malicious ALZ/UUE/XXE archive is scanned.
Successful exploitation allows arbitrary code execution, but requires that compressed file scanning is enabled.
The vulnerability has been confirmed in the following products:
* AhnLab V3Pro 2004 (AhnLab V3 VirusBlock 2005 international) (Build 6.0.0.457)
* AhnLab V3Net for Windows Server 6.0 (Build 6.0.0.457)
* AhnLab MyV3 with AzMain.dll 1.3.11.15
Prior versions may also be affected.
