Description Agostino Sarubbo gentoo-dev 2017-02-23 16:26:51 UTC
From https://bugzilla.redhat.com/show_bug.cgi?id=1422906:

An issue was discovered in icoutils. A buffer overflow was observed in the "decode_ne_resource_id" function in the "restable.c" source file. This is 
happening because the "len" parameter for memcpy is not checked for size and thus becomes a negative integer in the process, resulting in a failed 
memcpy. This affects wrestool.

From https://bugzilla.redhat.com/show_bug.cgi?id=1422907:

An issue was discovered in icoutils. A buffer overflow was observed in the "extract_icons" function in the "extract.c" sourcefile. This issue can be 
triggered by processing a corrupted ico file and will result in an icotool crash.
