Vulnerability Assessment Details

RHSA-2004-178: lha

Vulnerability Assessment Summary
Check for the version of the lha packages

Detailed Explanation for this Vulnerability Assessment

An updated LHA package that fixes several security vulnerabilities is now
available.

LHA is an archiving and compression utility for LHarc format archives.

Ulf Harnhammar discovered two stack buffer overflows and two directory
traversal flaws in LHA. A possible hacker could exploit the buffer overflows by
creating a carefully crafted LHA archive in such a way that arbitrary code
would be executed when the archive is tested or extracted by a victim. The
Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CVE-2004-0234 to this issue. A possible hacker could exploit
the directory traversal issues to create files as the victim outside of the
expected directory. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CVE-2004-0235 to this issue.

Users of LHA should update to this updated package which contains
backported patches not vulnerable to these issues.

Red Hat would like to thank Ulf Harnhammar for disclosing and providing
test cases and patches for these issues.
