Description

This security bulletin contains information about 5 secuirty vulnerabilities.


1) NULL pointer dereference (CVE-ID: CVE-2026-23952)

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

The vulnerability exists due to a NULL pointer dereference error in MSL parser within "comment" tag before image load. A remote user can pass specially crafted data to the application and perform a denial of service (DoS) attack.


2) 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.


3) Stack-based buffer overflow (CVE-ID: CVE-2026-23874)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error within infinite recursion in ProcessMSLScript. A local user can trigger stack-based buffer overflow and cause a denial of service condition on the target system.


4) Memory leak (CVE-ID: N/A)

The vulnerability allows a local user to perform DoS attack on the target system.

The vulnerability exists due memory leak in the "LoadOpenCLDeviceBenchmark()" function in MagickCore/opencl.c. A local administrator can force the application to leak memory and perform denial of service attack.


5) Release of invalid pointer or reference (CVE-ID: CVE-2026-22770)

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

The vulnerability exists due to invalid pointer in the BilateralBlurImage method. A remote attacker can cause a denial of service condition in the target system.
