Description
This security bulletin contains information about 9 vulnerabilities.
1) Uncontrolled Recursion (CVE-ID: CVE-2026-25971)
CWE-ID: CWE-674 - Uncontrolled Recursion
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to poorly bounded recursion in ProcessMSLScript. A local attacker can cause a denial of service condition on the target system.
2) Heap-based buffer overflow (CVE-ID: CVE-2026-33899)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
CVSSv4: 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/E:U/U:Green
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.
3) Integer overflow (CVE-ID: CVE-2026-33900)
CWE-ID: CWE-190 - Integer overflow
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 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.
4) Heap-based buffer overflow (CVE-ID: CVE-2026-33901)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
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 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.
5) Out-of-bounds read (CVE-ID: CVE-2026-33905)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/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 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)
CWE-ID: CWE-674 - Uncontrolled Recursion
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 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) Integer overflow (CVE-ID: CVE-2026-34238)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/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 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.
8) Heap-based buffer overflow (CVE-ID: CVE-2026-40310)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/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 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.
9) Use-after-free (CVE-ID: CVE-2026-40311)
CWE-ID: CWE-416 - Use After Free
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/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 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.
