    - -------------------------------------------------------------------------

    Package : apr
    Vulnerability : denial of service
    Problem type : remote
    Debian-specific: no
    CVE ID : CVE-2011-0419 CVE-2011-1928
    Debian bug : 627182


    The recent APR update DSA-2237-1 introduced a regression that could
    lead to an endless loop in the apr_fnmatch() function, causing a
    denial of service. This update fixes this problem (CVE-2011-1928).

    For reference, the description of the original DSA, which fixed
    CVE-2011-0419:

    A flaw was found in the APR library, which could be exploited through
    Apache HTTPD's mod_autoindex. If a directory indexed by mod_autoindex contained files with sufficiently long names, a remote attacker could
    send a carefully crafted request which would cause excessive CPU
    usage. This could be used in a denial of service attack.


    For the oldstable distribution (lenny), this problem has been fixed in
    version 1.2.12-5+lenny4.

    For the stable distribution (squeeze), this problem has been fixed in
    version 1.4.2-6+squeeze2.

    For the testing distribution (wheezy), this problem will be fixed in
    version 1.4.5-1.

    For the unstable distribution (sid), this problem will be fixed in
    version 1.4.5-1.

    We recommend that you upgrade your apr packages and restart the
    apache2 server.
