    CVE ID         : CVE-2014-2270
    Debian Bug     : 703993
    
    Several vulnerabilities have been found in file, a file type
    classification tool.
    
    Aaron Reffett reported a flaw in the way the file utility determined the
    type of Portable Executable (PE) format files, the executable format
    used on Windows. When processing a defective or intentionally prepared
    PE executable which contains invalid offset information, the
    file_strncmp routine will access memory that is out of bounds, causing
    file to crash. The Common Vulnerabilities and Exposures project ID
    CVE-2014-2270 has been assigned to identify this flaw.
    
    Mike Frysinger reported that file's rule for detecting AWK scripts
    significantly slows down file. The regular expression to detect AWK
    files contained two star operators, which could be exploited to cause
    excessive backtracking in the regex engine.
    
    For the oldstable distribution (squeeze), these problems have been fixed
    in version 5.04-5+squeeze4.
    
    For the stable distribution (wheezy), these problems have been fixed in
    version 5.11-2+deb7u2.
    
    For the testing distribution (jessie), these problems have been fixed in
    version 1:5.17-1.
    
    For the unstable distribution (sid), these problems have been fixed in
    version 1:5.17-1.
    
    We recommend that you upgrade your file packages.
