Vulnerability Assessment Details

RHSA-2004-323: lha

Vulnerability Assessment Summary
Check for the version of the lha packages

Detailed Explanation for this Vulnerability Assessment

An updated lha package that fixes a buffer overflow is now available.

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

Lukasz Wojtow discovered a stack-based buffer overflow in all versions
of lha up to and including version 1.14. A carefully created archive could
permit a possible hacker to execute arbitrary code when a victim extracts or tests
the archive. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CVE-2004-0769 to this issue.

Buffer overflows were discovered in the command line processing of all
versions of lha up to and including version 1.14. If a malicious user
could trick a victim into passing a specially crafted command line to the
lha command, it is possible that arbitrary code could be executed. The
Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
the names CVE-2004-0771 and CVE-2004-0694 to these issues.

Thomas Biege discovered a shell meta character command execution
vulnerability in all versions of lha up to and including 1.14. A possible hacker
could create a directory with shell meta characters in its name which could
lead to arbitrary command execution. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CVE-2004-0745 to
this issue.

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