[GLSA-200602-01] GStreamer FFmpeg plugin: Heap-based buffer overflow |
||
GStreamer FFmpeg plugin: Heap-based buffer overflow Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200602-01 (GStreamer FFmpeg test: Heap-based buffer overflow) The GStreamer FFmpeg test contains derived code from the FFmpeg library, which is vulnerable to a heap overflow in the "avcodec_default_get_buffer()" function discovered by Simon Kilvington (see GLSA 200601-06). Impact A remote attacker could entice a user to run an application using the GStreamer FFmpeg test on a maliciously crafted PIX_FMT_PAL8 format image file (like PNG images), possibly leading to the execution of arbitrary code with the permissions of the user running the application. Workaround There is no known workaround at this time.
