23) Heap-based buffer overflow

EUVDB-ID: #VU13548

Risk: Low

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2016-10092

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

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

The vulnerability exists due to heap-based buffer overflow in the readContigStripsIntoBuffer function in tif_unix.c when processing malicious input. A remote attacker can send a specially crafted image, trigger memory corruption and cause the service to crash.
