Multiple vendors libexif exif_data_load_data_entry() buffer overflow

multiple-libexif-exifdataloaddataentry-bo (34851) The risk level is classified as HighHigh Risk

Description:

Multiple vendors using libexif are vulnerable to a heap-based buffer overflow, caused by an integer overflow in the exif_data_load_data_entry() function. By persuading a victim to open a specially-crafted EXIF image, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the affected application to crash.
