Description

This security bulletin contains information about 7 vulnerabilities.


1) Heap-based buffer overflow (CVE-ID: CVE-2026-25897)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


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

The vulnerability exists due to a boundary error in the sun decoder. A remote attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and perform a denial of service (DoS) attack.


2) Out-of-bounds read (CVE-ID: CVE-2026-25898)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


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

The vulnerability exists due to a boundary condition within negative pixel index in UIL and XPM writer. A remote attacker can trigger an out-of-bounds read error and read contents of memory on the system or perform a denial of service (DoS) attack..


3) Stack-based buffer overflow (CVE-ID: CVE-2026-25968)

CWE-ID: CWE-121 - Stack-based buffer overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


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

The vulnerability exists due to a boundary error when processing the an attribute in msl.c. A remote unauthenticated attacker can trigger stack-based buffer overflow and gain access to sensitive information or perform a denial of service (DoS) attack.


4) Use-after-free (CVE-ID: CVE-2026-25983)

CWE-ID: CWE-416 - Use After Free

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in MSLStartElement in MSL decoder. A remote attacker can perform a denial of service (DoS) attack.


5) Out-of-bounds write (CVE-ID: CVE-2026-25986)

CWE-ID: CWE-787 - Out-of-bounds write

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error in ReadYUVImage() (coders/yuv.c) when processing malicious YUV 4:2:2 (NoInterlace) images. A remote attacker can trigger an out-of-bounds write and perform a denial of service (DoS) attack.


6) Out-of-bounds read (CVE-ID: CVE-2026-25987)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition in the MAP image decoder when processing crafted MAP files. A remote attacker can trigger an out-of-bounds read error and read contents of memory on the system.


7) Heap-based buffer overflow (CVE-ID: CVE-2026-26284)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


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

The vulnerability exists due to a boundary error in pcd decoder. A remote attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and gain acces to sensitive information or perform a denial of service (DoS) attack.
