Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) Heap-based buffer overflow (CVE-ID: CVE-2026-33899)

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

The vulnerability exists due to heap-based buffer overflow in the XML parser when parsing XML files. A remote attacker can send a specially crafted XML file to cause a denial of service.

A single zero byte may be written out of bounds during XML parsing.


2) Integer overflow (CVE-ID: CVE-2026-33900)

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

The vulnerability exists due to integer overflow or wraparound in the viff encoder when processing crafted input on 32-bit builds. A remote attacker can send a specially crafted file to trigger an out-of-bounds heap write and cause a denial of service.

Only 32-bit builds are vulnerable.


3) Out-of-bounds read (CVE-ID: CVE-2026-33905)

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

The vulnerability exists due to out-of-bounds read in the -sample operation when processing a specific offset supplied through the sample:offset define. A remote attacker can supply a crafted offset value to cause a denial of service.

User interaction is required to process the crafted input.


4) Uncontrolled Recursion (CVE-ID: CVE-2026-33908)

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

The vulnerability exists due to uncontrolled recursion in the DestroyXMLTree function when processing deeply nested XML input. A remote attacker can send a specially crafted XML file to cause a denial of service.


5) Integer overflow (CVE-ID: CVE-2026-34238)

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

The vulnerability exists due to integer overflow in the despeckle operation when processing crafted input on 32-bit builds. A remote attacker can trigger an out-of-bounds write to cause a denial of service.

Only 32-bit builds are vulnerable.


6) Use-after-free (CVE-ID: CVE-2026-40311)

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

The vulnerability exists due to use-after-free in XMP profile processing when parsing an invalid XMP profile. A remote attacker can trick the victim into opening a crafted file to cause a denial of service.

User interaction is required to process the crafted input.
