Description
This security bulletin contains information about 15 vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2026-32636)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in the NewXMLTree method. A remote attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and cause a denial of service condition on the target system.
2) Out-of-bounds write (CVE-ID: CVE-2026-33535)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input in the X11 display interaction path. A remote attacker can trigger an out-of-bounds write and perform a denial of service (DoS) attack the target system.
3) Stack-based buffer overflow (CVE-ID: CVE-2026-33536)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in InterpretImageFilename. A remote unauthenticated attacker can trigger stack-based buffer overflow and cause a denial of service condition on the target system.
4) 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.
5) 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.
6) 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.
7) 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.
8) 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.
9) 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.
10) 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.
11) Heap-based buffer overflow (CVE-ID: CVE-2026-40169)
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to heap-based buffer overflow in the YAML and JSON encoders when writing yaml or json output. A remote attacker can process a crafted image to cause a denial of service.
12) Heap-based buffer overflow (CVE-ID: CVE-2026-40183)
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to heap-based buffer overflow in the JXL encoder when encoding an image as 16-bit floats. 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.
13) 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.
14) 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.
15) Off-by-one (CVE-ID: CVE-2026-40312)
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to an off-by-one error in the MSL decoder when parsing a malicious MSL file. A remote attacker can supply a specially crafted MSL file to cause a denial of service.
