    Package        : curl
    Vulnerability  : unchecked ssl certificate host name
    Problem type   : remote
    Debian-specific: no
    CVE ID         : CVE-2013-4545
    
    The update for curl in DSA-2798-1 uncovered a regression affecting the
    curl command line tool behaviour (#729965). This update disables host
    verification too when using the --insecure option.
    
    For the oldstable distribution (squeeze), this problem has been fixed in
    version 7.21.0-2.1+squeeze6.
    
    For the stable distribution (wheezy), this problem has been fixed in
    version 7.26.0-1+wheezy6.
    
    For the testing (jessie) and unstable (sid) distributions, the curl
    command line tool behaves as expected with the --insecure option.
    
    For reference the original advisory text follows.
    
    Scott Cantor discovered that curl, a file retrieval tool, would disable
    the CURLOPT_SSLVERIFYHOST check when the CURLOPT_SSL_VERIFYPEER setting
    was disabled.  This would also disable ssl certificate host name checks
    when it should have only disabled verification of the certificate trust
    chain.
    
    The default configuration for the curl package is not affected by this
    issue since CURLOPT_SSLVERIFYPEER is enabled by default.
    
    For the oldstable distribution (squeeze), this problem has been fixed in
    version 7.21.0-2.1+squeeze5.
    
    For the stable distribution (wheezy), this problem has been fixed in
    version 7.26.0-1+wheezy5.
    
    For the testing (jessie) and unstable (sid) distributions, this problem
    has been fixed in version 7.33.0-1.
    
    We recommend that you upgrade your curl packages.
