Description
This security bulletin contains information about 7 vulnerabilities.
1) Memory leak (CVE-ID: CVE-2026-56366)
CWE-ID: CWE-401 - Missing release of memory after effective lifetime
CVSSv4: 5.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to perform DoS attack on the target system.
The vulnerability exists due memory leak in the META reader when processing the APP1JPEG input path. A remote attacker can force the application to leak memory and perform denial of service attack.
2) Use-after-free (CVE-ID: CVE-2026-56373)
CWE-ID: CWE-416 - Use After Free
CVSSv4: 6.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in the PDB decoder. A remote attacker can perform a denial of service (DoS) attack.
3) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2026-61465)
CWE-ID: CWE-770 - Allocation of Resources Without Limits or Throttling
CVSSv4: 4.6 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to allocation of resources without limits or throttling in matrix-backed operations when processing crafted image content. A remote attacker can trigger matrix-based operations such as -canny to cause a denial of service.
User interaction is required to process the crafted image content.
4) Use-after-free (CVE-ID: CVE-2026-61857)
CWE-ID: CWE-416 - Use After Free
CVSSv4: 6.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to use-after-free in the XMP profile parser when parsing an XMP profile. A remote attacker can supply a crafted XMP profile to cause a denial of service.
5) Missing Authorization (CVE-ID: CVE-2026-61858)
CWE-ID: CWE-862 - Missing Authorization
CVSSv4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a local user to bypass policy restrictions and write to a disallowed path.
The vulnerability exists due to missing authorization in the APNG encoder and external delegates when writing files. A local user can trigger crafted processing to bypass policy restrictions and write to a disallowed path.
6) Use-after-free (CVE-ID: CVE-2026-61861)
CWE-ID: CWE-416 - Use After Free
CVSSv4: 6.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to use-after-free in the FormatMagickCaption method when handling memory allocation failure. A remote attacker can trigger a memory allocation failure to cause a denial of service.
7) Memory leak (CVE-ID: CVE-2026-61870)
CWE-ID: CWE-401 - Missing release of memory after effective lifetime
CVSSv4: 2 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to missing release of memory after effective lifetime in the VIFF encoder when handling allocation failures. A remote attacker can trigger an allocation failure to cause a denial of service.
