    PACKAGE : lha
    SUMMARY : Buffer overflow and directory traversal vulnerabilities
    DATE : 2004-05-06 18:20:00

    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.
