    Vulnerability  : heap overflow
    Problem type   : remote

    A heap overflow has been discovered in ClamAV, a virus scanner, which
    could allow an attacker to execute arbitrary code by sending a carefully
    crafted UPX-encoded executable to a system runnig ClamAV. In addition,
    other potential overflows have been corrected.
    
    Packages for the ARM architecture were not available when DSA 947-1 was
    released; these packages are now available. Also, DSA 947-1 incorrectly
    identified the package version which corrected these issues in the
    unstable distribution (sid).
    
    The old stable distribution (woody) does not include ClamAV.
    
    For the stable distribution (sarge) this problem has been fixed in
    version 0.84-2.sarge.7.
    
    For the unstable distribution (sid) this problem has been fixed in
    version 0.88-1.
    
    We recommend that you upgrade your clamav package immediately.
