Nikita Popov 56e3e6f135 Implement a cache for exif tag name lookups 2019-10-18 16:54:56 +02:00
Nikita Popov e5324a2484 Limit the amount of errors generated during exif parsing 
Emitting errors is fairly expensive, to the point that parsing
a file with a huge number of invalid tags can take seconds.
Generating ten thousand errors is unlikely to help anybody, but
constitutes a potential DOS vector.

Nikita Popov 0701835c01 Fix multiple leaks in exif_read_data() 
This fixes two leaks related to duplicate tags, as well as a leak
of zero-length FMT_(S)BYTE with non-null value. This can show up
for MAKERNOTE values where the original length is non-zero, but
the first character is a null byte.

Nikita Popov 0fa13028cb Fix out-of-bounds read in exif tag reading 
This issue was recently introduced in c739023a50,
when the restriction that components>0 has been relaxed. We now need
to make sure that any tags that expect at least one component check
that this is the case.

Nikita Popov 68fd435ba8 Fixed bug #78333 
Don't dereference float/double values at unknown address, instead
memcpy it into an aligned stack slot and dereference that.
