Description

Two vulnerabilities have been reported in FFmpeg, which can be exploited by malicious people to cause a DoS (Denial of Service).

1) A NULL pointer dereference error within the "decode_frame()" function (libavcodec/dxa.c) can be exploited to cause a crash.

2) An out-of-bounds read error within the "h261_decode_mb()" function (libavcodec/h261dec.c) can be exploited to cause a crash.


Solution:
Fixed in the git repository.

@maintainer(s): after the bump, in case we need to stabilize the package, please say explicitly if it is ready for the stabilization or not.

No CVEs requested/assigned, it seems.
