Description
This security bulletin contains information about 8 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) Heap-based buffer overflow (CVE-ID: CVE-2026-33901)
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to a heap-based buffer overflow in the MVG decoder when processing a crafted image. A remote attacker can send a specially crafted image to cause a denial of service.
The issue could result in an out-of-bounds write.
4) Uncontrolled Recursion (CVE-ID: CVE-2026-33902)
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to uncontrolled recursion in the FX expression parser when parsing deeply nested expressions. A remote attacker can provide a deeply nested expression to cause a denial of service.
User interaction is required to process the crafted expression.
5) 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.
6) 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.
7) Heap-based buffer overflow (CVE-ID: CVE-2026-40310)
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to heap-based buffer overflow in the JP2 encoder when processing input with an invalid sampling index. A remote attacker can trick the victim into processing a crafted file to cause a denial of service.
User interaction is required to process the crafted input.
8) 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.
