Libexif exif_data_load_data_entry integer overflow
| libexif-exifdataloaddata-integer-overflow (34233) |  High Risk |
Description:
Libexif is vulnerable to an integer overflow, caused by improper validation of doff and s values by the exif_data_load_data_entry() function. By creating a specially-crafted EXIF image, a remote attacker could exploit this vulnerability to execute arbitrary code on the system or cause the application to crash, if the attacker could persuade the victim to open the malicious image.
