    CVE ID         : CVE-2006-4334 CVE-2006-4335 CVE-2006-4336 CVE-2006-4337 CVE-2006-4338
    
    Tavis Ormandy from the Google Security Team discovered several
    vulnerabilities in gzip, the GNU compression utility. The Common
    Vulnerabilities and Exposures project identifies the following problems:
     
    CVE-2006-4334
    
        A null pointer dereference may lead to denial of service if gzip is
        used in an automated manner.
    
    CVE-2006-4335
    
        Missing boundary checks may lead to stack modification, allowing
        execution of arbitrary code.
    
    CVE-2006-4336
    
        A buffer underflow in the pack support code may lead to execution of
        arbitrary code.
    
    CVE-2006-4337
    
        A buffer underflow in the LZH support code may lead to execution of
        arbitrary code.
    
    CVE-2006-4338
    
        An infinite loop may lead to denial of service if gzip is used in
        an automated manner.
    
    For the stable distribution (sarge) these problems have been fixed in
    version 1.3.5-10sarge2.
    
    For the unstable distribution (sid) these problems have been fixed in
    version 1.3.5-15.
    
    We recommend that you upgrade your gzip package.
