Description

This security bulletin contains information about 3 secuirty vulnerabilities.

1) Integer overflow (CVE-ID: CVE-2025-62171)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to an integer overflow in coders/bmp.c caused by an incomplete fox for #VU114417 (CVE-2025-57803). A remote attacker can pass specially crafted image to the application, trigger an integer overflow and perform a denial of service (DoS) attack.

The vulnerability affects only 32-bit systems with certain resource limits. 

2) Integer overflow (CVE-ID: CVE-2025-57803)

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

The vulnerability exists due to integer overflow in the BMP encoder’s scanline-stride computation. A remote user can pass specially crafted data to the application, trigger integer overflow and execute arbitrary code on the target system.

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

3) Heap-based buffer overflow (CVE-ID: CVE-2026-23876)

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

The vulnerability exists due to a boundary error in the XBM image decoder. A remote attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and execute arbitrary code on the target system.

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