CVE-2016-4544

CRITICAL

PHP < 5.5.35, 5.6.x < 5.6.21, 7.x < 7.0.6 - Denial of Service via TIFF Header Processing

Title source: llm
STIX 2.1

Description

The exif_process_TIFF_in_JPEG function in ext/exif/exif.c in PHP before 5.5.35, 5.6.x before 5.6.21, and 7.x before 7.0.6 does not validate TIFF start data, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via crafted header data.
