Summary

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.

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

    descriptionMultiple vulnerabilities has been discovered and corrected in ffmpeg : The decode_init function in libavcodec/huffyuv.c in FFmpeg before 1.1 allows remote attackers to have an unspecified impact via a crafted width in huffyuv data with the predictor set to median and the colorspace set to YUV422P, which triggers an out-of-bounds array access (CVE-2013-0848). The parse_picture_segment function in libavcodec/pgssubdec.c in FFmpeg before 1.1 allows remote attackers to have an unspecified impact via crafted RLE data, which triggers an out-of-bounds array access (CVE-2013-0852). The ff_er_frame_end function in libavcodec/error_resilience.c in FFmpeg before 1.0.4 and 1.1.x before 1.1.1 does not properly verify that a frame is fully initialized, which allows remote attackers to trigger a NULL pointer dereference via crafted picture data (CVE-2013-0860). The mm_decode_inter function in mmvideo.c in libavcodec in FFmpeg before 1.2.1 does not validate the relationship between a horizontal coordinate and a width value, which allows remote attackers to cause a denial of service (out-of-bounds array access and application crash) via crafted American Laser Games (ALG) MM Video data (CVE-2013-3672). The cdg_decode_frame function in cdgraphics.c in libavcodec in FFmpeg before 1.2.1 does not validate the presence of non-header data in a buffer, which allows remote attackers to cause a denial of service (out-of-bounds array access and application crash) via crafted CD Graphics Video data (CVE-2013-3674). 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 (CVE-2013-7020). The updated packages have been upgraded to the 0.10.15 version which is not vulnerable to these issues.
