3) Description of Vulnerability
Secunia Research has discovered a vulnerability in WinACE, which can
be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a boundary error when reading an
overly large ARJ header block into a fixed-sized heap buffer. This can
be exploited to cause a heap-based buffer overflow.
Successful exploitation allows execution of arbitrary code when a
malicious ARJ archive is opened.
The Common Vulnerabilities and Exposures (CVE) project has assigned
CVE-2006-0813 for the vulnerability.
