    Package        : flex
    CVE ID         : CVE-2016-6354
    Debian Bug     : 832768 835542
    
    It was reported that the update for flex as released in DSA-3653-1 did
    not completely address CVE-2016-6354 as intended due to problems in the
    patch handling and regenerated files during the build. Additionally a
    regression was introduced, causing new warnings when compiling flex
    generated code. Updated packages are now available to address these
    problems. For reference, the relevant part of the original advisory
    text follows.
    
    Alexander Sulfrian discovered a buffer overflow in the
    yy_get_next_buffer() function generated by Flex, which may result in
    denial of service and potentially the execution of code if operating on
    data from untrusted sources.
    
    Affected applications need to be rebuild.
    
    For the stable distribution (jessie), this problem has been fixed in
    version 2.5.39-8+deb8u2.
    
    We recommend that you upgrade your flex packages.
