Updated on: 2004-09-01
Product: Red Hat Enterprise Linux
Obsoletes: RHSA-2004:178
CVE Names: CAN-2004-0769 CAN-2004-0771 CAN-2004-0694 CAN-2004-0745
----------------------------------------------------------------------
1. Summary:
An updated lha package that fixes a buffer overflow is now available.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Desktop version 3 - i386, x86_64
Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64
3. Problem description:
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 allow an attacker 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 CAN-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 CAN-2004-0771 and CAN-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. An attacker 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 CAN-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.
