Description
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer underflow in the exif_entry_get_value function in exif-entry.c in the EXIF Tag Parsing Library. A remote attacker can create a specially crafted file and execute arbitrary code via vectors involving a crafted buffer-size parameter during the formatting of an EXIF tag, leading to a heap-based buffer overflow.
