1) Out-of-bounds read

EUVDB-ID: #VU8078

Risk: Low

CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2017-11714

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

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

The weakness exists due to out-of-bounds read in the igc_reloc_struct_ptr function in psi/igc.c when handling references to the scanner state structure by psi/ztoken.c. A remote attacker can send a specially crafted PostScript document, trick the victim into processing it, trigger out-of-bounds read and cause the application to crash.

Successful exploitation of the vulnerability results in denial of service.

Mitigation

Update to the latest version.
