(UnAce: Buffer overflow and directory traversal vulnerabilities)


    Ulf Harnhammar discovered that UnAce suffers from buffer overflows
    when testing, unpacking or listing specially crafted ACE archives
    (CAN-2005-0160). He also found out that UnAce is vulnerable to
    directory traversal attacks, if an archive contains "./.." sequences or
    absolute filenames (CAN-2005-0161).
  
Impact

    An attacker could exploit the buffer overflows to execute
    malicious code or the directory traversals to overwrite arbitrary
    files.
  
Workaround

    There is no known workaround at this time.

Solution: 
    All UnAce users should upgrade to the latest available 1.2
    version:
    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-arch/unace-1.2b-r1"
  

Risk factor : Medium
