Vulnerability identifier: #VU16586

CSH Severity: Low

CVSS v4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]

CVE-ID: CVE-2018-20184

CWE-ID: CWE-122

Exploitation vector: Remote access

Exploit availability: No public exploit available

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 WriteTGAImage function of tga.c when processing malicious input. A remote attacker can cause the service to crash via a crafted image file, because the number of rows or columns can exceed the pixel-dimension restrictions of the TGA specification.
