Description

This security bulletin contains information about 6 vulnerabilities.


1) Heap-based buffer overflow (CVE-ID: CVE-2026-53465)

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

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


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to heap-based buffer overflow in the SF3 encoder when encoding a crafted multi-frame image. A remote attacker can supply a specially crafted multi-frame image for encoding to cause a denial of service.


2) Memory leak (CVE-ID: CVE-2026-53464)

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

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


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 wand option parser when processing invalid arguments. A remote attacker can provide invalid options to cause a denial of service.


3) NULL pointer dereference (CVE-ID: CVE-2026-53463)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: 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/E:U/U:Clear


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to null pointer dereference in distort operation when processing incorrect arguments. A remote attacker can pass incorrect arguments to cause a denial of service.

User interaction is required to process the crafted input.


4) Use-after-free (CVE-ID: CVE-2026-53462)

CWE-ID: CWE-416 - Use After Free

CVSSv4: 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/E:U/U:Green


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to use-after-free in CheckPrimitiveExtent when an allocation fails. A remote attacker can trigger an allocation failure condition to cause a denial of service.


5) Out-of-bounds write (CVE-ID: CVE-2026-53461)

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:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to out-of-bounds write in the ICON decoder when parsing a crafted ICON image. A remote attacker can supply a specially crafted ICON image to cause a denial of service.


6) Input validation error (CVE-ID: CVE-2026-53460)

CWE-ID: CWE-20 - Improper input validation

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


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to improper input validation in AcquireAlignedMemory when processing memory allocation requests. A remote attacker can trigger excessive memory allocation to cause a denial of service.
