Description : LHA is an archiving and compression utility for LHarc format archives. LHA is mostly used in the DOS world, but can be used under Linux to extract DOS files from LHA archives. Install the lha package if you need to extract DOS files from LHA archives. --------------------------------------------------------------------- Update Information: 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.
