    Package        : arc
    Vulnerability  : insecure temporary file
    Problem type   : local
    Debian-specific: no
    CVE ID         : CAN-2005-2945 CAN-2005-2992
    
    Two vulnerabilities have been discovered in the ARC archive program
    under Unix.  The Common Vulnerabilities and Exposures project
    identifies the following problems:
    
    CAN-2005-2945
    
        Eric Romang discovered that the ARC archive program under Unix
        creates a temporary file with insecure permissions which may lead
        to an attacker stealing sensitive information.
    
    CAN-2005-2992
    
        Joey Schulze discovered that the temporary file was created in an
        insecure fashion as well, leaving it open to a classic symlink
        attack.
    
    The old stable distribution (woody) does not contain arc packages.
    
    For the stable distribution (sarge) these problems have been fixed in
    version 5.21l-1sarge1.
    
    For the unstable distribution (sid) these problems have been fixed in
    version 5.21m-1.
    
    We recommend that you upgrade your arc package.
