-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : lha SUMMARY : Buffer overflow and directory traversal vulnerabilities DATE : 2004-05-06 18:20:00 ID : CLA-2004:840 RELEVANT RELEASES : 8, 9 - ------------------------------------------------------------------------- DESCRIPTION Lha is an archiving and compression utility for LHarc format archives. Ulf Härnhammar discovered a buffer overflow[1] and a directory traversal [2]vulnerability in the lha utility. Both vulnerabilities can be exploited by an attacker with the use of specially crafted LHarc archives. When processed by lha, these files may cause it to execute arbitrary code (exploiting the buffer overflow vulnerability) or overwrite arbitrary files if the user unpacking the malicious archive has sufficient filesystem permissions to do so (exploiting the directory traversal vulnerability). This update fixes both issues. SOLUTION All users of the lha utility should upgrade.
