Description
This security bulletin contains information about 16 secuirty vulnerabilities.
1) 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.
2) Stack-based buffer overflow (CVE-ID: CVE-2026-28494)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in morphology kernel parsing functions. A remote 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.
3) Heap-based buffer overflow (CVE-ID: CVE-2026-28686)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in the PCL encode. A remote 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) Use-after-free (CVE-ID: CVE-2026-28687)
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to use-after-free in the MSL decoder when parsing a crafted MSL file. A remote attacker can supply a crafted MSL file to cause a denial of service.
5) Use-after-free (CVE-ID: CVE-2026-28688)
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to use-after-free in the MSL encoder when processing crafted MSL input. A remote attacker can trigger a double destruction of a cloned image to cause a denial of service.
6) Time-of-check Time-of-use (TOCTOU) Race Condition (CVE-ID: CVE-2026-28689)
The vulnerability allows a remote attacker 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 remote user can bypass authentication on the system.
7) Stack-based buffer overflow (CVE-ID: CVE-2026-28690)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the MNG encoder. A remote 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) 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.
9) 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.
10) 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.
11) Heap-based buffer overflow (CVE-ID: CVE-2026-30883)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when writing extremely large image profile in the PNG encoder. A remote 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.
12) Stack-based buffer overflow (CVE-ID: CVE-2026-30929)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to a boundary error in MagnifyImage. A remote unauthenticated attacker can trigger stack-based buffer overflow and corrupt the stack on the target system.
13) Heap-based buffer overflow (CVE-ID: CVE-2026-30931)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in the UHDR encoder. A remote 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.
14) Heap-based buffer overflow (CVE-ID: CVE-2026-30936)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in the WaveletDenoiseImage method. A remote 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.
15) Heap-based buffer overflow (CVE-ID: CVE-2026-30937)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in XWD encoder. A remote 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.
16) Stack-based buffer overflow (CVE-ID: CVE-2026-32259)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to a boundary error in sixel encoder. A remote unauthenticated attacker can trigger stack-based buffer overflow and corrupt the stack on the target system.
