CVE-2014-9317
HighSummary
The decode_ihdr_chunk function in libavcodec/pngdec.c in FFMpeg before 2.1.6, 2.2.x through 2.3.x, and 2.4.x before 2.4.4 allows remote attackers to cause a denial of service (out-of-bounds heap access) and possibly have other unspecified impact via an IDAT before an IHDR in a PNG file.
Risk Assessment
Attackers may exploit this vulnerability to disrupt system operations, potentially leading to service downtime. It may also pose a risk to the integrity of data processed by the application.
Recommendation
It is recommended to update FFMpeg to version 2.1.6 or later to mitigate this vulnerability. Additionally, it is advisable to monitor and analyze PNG files before processing them.
