Description

This security bulletin contains information about 11 secuirty vulnerabilities.


1) Heap-based buffer overflow (CVE-ID: CVE-2026-31853)

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

The vulnerability exists due to a boundary error on 32-bit systems in SFW decoder. A local attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and cause a denial of service condition on the target system.


2) Integer overflow (CVE-ID: CVE-2026-28493)

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

The vulnerability exists due to integer overflow in SIXEL decoder. A remote attacker can pass specially crafted data to the application, trigger integer overflow and cause a denial of service condition on the target system.


3) Heap-based buffer overflow (CVE-ID: CVE-2026-30937)

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

The vulnerability exists due to a boundary error in XWD encoder. A local attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and cause a denial of service condition on the target system.


4) Integer overflow (CVE-ID: CVE-2026-28693)

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

The vulnerability exists due to integer overflow in DIB coder. A remote attacker 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.


5) Out-of-bounds read (CVE-ID: CVE-2026-28692)

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

The vulnerability exists due to a boundary condition in MAT decoder within 32-bit arithmetic. A remote attacker can trigger an out-of-bounds read error and gain access to sensitive information or perform a denial of service (DoS) attack.


6) Access of Uninitialized Pointer (CVE-ID: CVE-2026-28691)

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

The vulnerability exists due to uninitialized pointer dereference in the JBIG decoder. A remote attacker can perform a denial of service (DoS) attack on the system.


7) Stack-based buffer overflow (CVE-ID: CVE-2026-28690)

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

The vulnerability exists due to a boundary error in the MNG encoder. A local attacker can trigger 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.


8) Time-of-check Time-of-use (TOCTOU) Race Condition (CVE-ID: CVE-2026-28689)

The vulnerability allows a local user to compromise the target system.

The vulnerability exists due to a time-of-check, time-of-use (TOCTOU) race condition in domain="path" authorization. A local user can bypass authentication on the system.


9) Heap-based buffer overflow (CVE-ID: CVE-2026-28686)

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

The vulnerability exists due to a boundary error in the PCL encode. A local attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and cause a denial of service condition on the target system.


10) Stack-based buffer overflow (CVE-ID: CVE-2026-28494)

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

The vulnerability exists due to a boundary error in morphology kernel parsing functions. A local unauthenticated attacker can trigger 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.


11) Heap-based buffer overflow (CVE-ID: CVE-2026-30936)

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

The vulnerability exists due to a boundary error in the WaveletDenoiseImage method. A local attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and cause a denial of service condition on the target system.
