CVE-2012-2814.patch
CVE-2012-2814
Fixed some buffer overflows in exif_entry_format_value()
Created attachment 498454 [details]
CVE-2012-2840.patch
CVE-2012-2840
Fixed an off-by-one error in exif_convert_utf16_to_utf8()
This can cause a one-byte NUL write past the end of the buffer.
Created attachment 498455 [details]
CVE-2012-2813.patch
CVE-2012-2813
Don't read past the end of a tag when converting from UTF-16
Created attachment 498456 [details]
CVE-2012-2812.patch
CVE-2012-2812
Fixed an out of bounds read on corrupted input.
The EXIF_TAG_COPYRIGHT tag ought to be, but perhaps is not,
NUL-terminated.
Created attachment 498457 [details]
CVE-2012-2841.patch
CVE-2012-2841
Fixed a buffer overflow problem in exif_entry_get_value
If the application passed in a buffer length of 0, then it would
be treated as the buffer had unlimited length.

CVE-2012-2836.patch
CVE-2012-2836
Fix a buffer overflow on corrupt EXIF data.
This fixes bug #3434540 and fixes part of CVE-2012-2836
Created attachment 498459 [details]
CVE-2012-2836-2.patch
CVE-2012-2836
Fix a buffer overflow on corrupted JPEG data
An unsigned data length might wrap around when decremented
below zero, bypassing sanity checks on length.
This code path can probably only occur if exif_data_load_data()
is called directly by the application on data that wasn't parsed
by libexif itself.
This solves the other part of CVE-2012-2836
Created attachment 498460 [details]
CVE-2012-2837.patch
