Description
This security bulletin contains information about 8 vulnerabilities.
1) Integer overflow (CVE-ID: CVE-2026-53466)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: 6.9 [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]
The vulnerability allows a remote attacker to cause a denial of service and disclose sensitive information.
The vulnerability exists due to integer overflow in the XCF decoder when parsing a crafted image. A remote attacker can supply a specially crafted image to cause a denial of service and disclose sensitive information.
2) Information disclosure (CVE-ID: CVE-2026-53467)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: 6.9 [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]
The vulnerability allows a remote attacker to disclose sensitive information.
The vulnerability exists due to heap information disclosure in the MNG decoder when parsing crafted MNG images. A remote attacker can supply a crafted MNG image to disclose sensitive information.
3) Use-after-free (CVE-ID: CVE-2026-55510)
CWE-ID: CWE-416 - Use After Free
CVSSv4: 6.7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/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 8BIM profile handling code when identifying a crafted image. A remote attacker can trick the victim into processing a specially crafted image to cause a denial of service.
User interaction is required to process the crafted image.
4) Out-of-bounds write (CVE-ID: CVE-2026-55577)
CWE-ID: CWE-787 - Out-of-bounds write
CVSSv4: 8.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to out-of-bounds write in the MVG decoder when processing a crafted image. A remote attacker can supply a specially crafted image to cause a denial of service.
5) Uncontrolled Recursion (CVE-ID: CVE-2026-55594)
CWE-ID: CWE-674 - Uncontrolled Recursion
CVSSv4: 6.9 [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]
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to uncontrolled recursion in the MVG decoder when parsing a crafted image. A remote attacker can supply a crafted image to cause a denial of service.
6) Infinite loop (CVE-ID: CVE-2026-55595)
CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')
CVSSv4: 5.6 [CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to loop with unreachable exit condition in the connected-components option when processing invalid arguments. A remote attacker can provide invalid arguments to cause a denial of service.
User interaction is required to supply the invalid arguments.
7) Out-of-bounds write (CVE-ID: CVE-2026-55597)
CWE-ID: CWE-787 - Out-of-bounds write
CVSSv4: 6.7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to out-of-bounds write in the JP2 encoder when parsing a crafted JP2 file. A remote attacker can trick the victim into opening a crafted file to cause a denial of service.
User interaction is required to open a crafted file.
8) Missing Authorization (CVE-ID: CVE-2026-55628)
CWE-ID: CWE-862 - Missing Authorization
CVSSv4: 6.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a local user to read and write files in paths disallowed by the security policy.
The vulnerability exists due to missing authorization in the -concatenate operation when processing file paths. A local user can invoke the concatenate operation with disallowed paths to read and write files in paths disallowed by the security policy.
