Michael Niedermayer	61c68000ed	avcodec/mjpegdec: Add some sanity checks to ljpeg_decode_rgb_scan() These prevent the rgb ljpeg code from being run on parameters that it doesnt support. No testcase available but it seems possible to trigger these. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Clément Bœsch	3e1f507f3e	avcodec: make avcodec_close() more tolerant. See previous commit.	11 years ago
Michael Niedermayer	9cbb3fce59	avcodec/avpacket: zero memory in av_packet_new_side_data() This ensures that no uninitialized bytes cause non-deterministic behavior. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Nicolas George	04dcdc4640	lavc/avfft: init context to 0. Prevent an invalid free in case of init failure.	11 years ago
Nicolas George	d7ccfe58e3	lavc/libvorbisdec: do not return empty frames. Some parts of the code have been known to react badly to empty frames; they should not, but there is no need to take risks.	11 years ago
Clément Bœsch	2c1eb38e5e	avcodec: fix AVpacket → AVPacket typo.	11 years ago
Michael Niedermayer	2ffead98dd	avcodec: add emuedge_linesize_type Currently all uses of the emu edge code as well as the code itself assume int linesize changing some but not changing all would introduce a security issue once all use this typedef a simple search and replace can be done to switch them all to ptrdiff_t Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Martin Storsjö	a711a2cb47	mpegvideo: Avoid 32-bit wrapping of linesize multiplications This makes sure that linesize * start_y doesn't overflow, so that emulated_edge_mc can get back the original value if needed. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago

Michael Niedermayer	8088d6f5f1	avcodec/pictordec: run av_image_check_size() unconditionally This ensures that no invalid size leaks through (This issue is hypothetical, ive no testcase) Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	af11fa5409	mjpegb: Detect changing number of planes in interlaced video Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Martin Storsjö	35cbc98b72	alac: Check that the channels fit at the given offset The code tries to decode a number of channels at the offset given by the ff_alac_channel_layout_offsets table. Even if the number of channels decoded so far doesn't exceed the total number of channels, we need to check that we actually can decode that number of channels at this offset as well. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Martin Storsjö	f7c5883126	alac: Limit max_samples_per_frame Otherwise buffer size calculations in allocate_buffers could overflow later, making the code think a large enough buffer actually was allocated. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago

Anton Khirnov	5f7aecde02	pictordec: break out of both decoding loops when y drops below 0 Otherwise picmemset can get called with negative y, resulting in an invalid write. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	11 years ago
