Michael Niedermayer	56abf35151	avformat/nutdec: Fix use of uinitialized value Fixes CID1041175 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Luca Barbato	254f3daba4	nut: Make sure to clean up on read_header failure Based on Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com> work. CC: libav-stable@libav.org	10 years ago
Andreas Cadhalpun	b34257eefd	nut: Check chapter creation in decode_info_header This fixes a segmentation fault when accessing the metadata. Signed-off-by: Luca Barbato <lu_zero@gentoo.org> CC: libav-stable@libav.org	10 years ago
Andreas Cadhalpun	7c24ca1bda	nutdec: fix illegal count check in decode_main_header The existing check has two problems: 1) i + count can overflow, so that the check '< 256' returns true. 2) In the (i == 'N') case occurs a j-- so that the loop runs once more. This can trigger the assertion 'nut->header_len[0] == 0' or cause segmentation faults or infinite hangs.
