EUVDB-ID: #VU12905

Risk: Low

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2016-10158

CWE-ID: CWE-682 - Incorrect Calculation

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists in the exif_convert_any_to_int function in ext/exif/exif.c due to numeric errors. A remote attacker can submit specially crafted EXIF data that triggers an attempt to divide the minimum representable negative integer by -1 and cause the service to crash.

Mitigation

Update the affected packages.
