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 can 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.
