Debian : Security Vulnerabilities, CVEs, Published In December 2013

The read_header function in libavcodec/ffv1dec.c in FFmpeg before 2.1 does not properly enforce certain bit-count and colorspace constraints, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted FFV1 data.

denyhosts 2.6 uses an incorrect regular expression when analyzing authentication logs, which allows remote attackers to cause a denial of service (incorrect block of IP addresses) via crafted login names.

The GnuTLS backend in libcurl 7.21.4 through 7.33.0, when disabling digital signature verification (CURLOPT_SSL_VERIFYPEER), also disables the CURLOPT_SSL_VERIFYHOST check for CN or SAN host name fields, which makes it easier for remote attackers to spoof servers and conduct man-in-the-middle (MITM) attacks.

nbd-server in Network Block Device (nbd) before 3.5 does not properly check IP addresses, which might allow remote attackers to bypass intended access restrictions via an IP address that has a partial match in the authfile configuration file.

Debian adequate before 0.8.1, when run by root with the --user option, allows local users to hijack the tty and possibly gain privileges via the TIOCSTI ioctl.

The atrac3_decode_init function in libavcodec/atrac3.c in FFmpeg before 1.0.4 allows remote attackers to have an unspecified impact via ATRAC3 data with the joint stereo coding mode set and fewer than two channels.
