SB2026012365 - openEuler 24.03 LTS SP2 update for ghostscript

Description

This security bulletin contains information about 3 secuirty vulnerabilities.

1) Stack-based buffer overflow (CVE-ID: CVE-2025-59798)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the pdf_write_cmap() function in devices/vector/gdevpdtw.c. A remote attacker can trick the victim into opening a specially crafted file to trigger a stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

2) Stack-based buffer overflow (CVE-ID: CVE-2025-59799)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the pdfmark_coerce_dest() function in devices/vector/gdevpdfm.c. A remote attacker can trick the victim into opening a specially crafted file to trigger a stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

3) Integer overflow (CVE-ID: CVE-2025-59800)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to integer overflow within the ocr_begin_page() function in devices/gdevpdfocr.c. A remote attacker can pass specially crafted data to the application, trigger an integer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
