Description

This security bulletin contains information about 2 vulnerabilities.


1) Use of Potentially Dangerous Function (CVE-ID: CVE-2023-43115)

CWE-ID: CWE-676 - Use of Potentially Dangerous Function

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber


The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists in gdevijs.c in GhostPDL due to the way PostScript handles IJS device change. A remote attacker can trick the victim to open a specially crafted document that will switch to the IJS device, start the IJS server and execute arbitrary commands on the system.


2) Integer overflow (CVE-ID: CVE-2023-38560)

CWE-ID: CWE-190 - Integer overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to crash the application.

The vulnerability exists due to integer overflow within the pl_glyph_name() function in pcl/pl/plfont.c when converting PCL files to PDF format. A remote attacker can pass a specially crafted PLC file to the application, trigger an integer overflow and perform a denial of service (DoS) attack.
