LHA has been reported prone to multiple vulnerabilities that may allow a malicious archive to execute arbitrary code or corrupt arbitrary files when the archive is operated on. The first issues reported have been assigned the CVE candidate identifier (CAN-2004-0234). LHA is reported prone to two stack-based buffer-overflow vulnerabilities. An attacker may exploit these vulnerabilities to execute supplied instructions with the privileges of the user who invoked the affected LHA utility. The second set of issues has been assigned CVE candidate identifier (CAN-2004-0235). In addition to the buffer-overflow vulnerabilities that were reported, LHA has been reported prone to several directory-traversal issues. An attacker may likely exploit these directory-traversal vulnerabilities to corrupt/overwrite files in the context of the user who is running the affected LHA utility. **NOTE: Reportedly, this issue may also cause a denial-of-service condition in the ClearSwift MAILsweeper products...
