Description
This security bulletin contains information about 10 vulnerabilities.
1) 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.
2) Heap-based buffer overflow (CVE-ID: CVE-2026-40169)
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 YAML and JSON encoders when writing yaml or json output. A remote attacker can process a crafted image to cause a denial of service.
3) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2026-45031)
CWE-ID: CWE-770 - Allocation of Resources Without Limits or Throttling
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 allocation of resources without limits or throttling in the PSD decoder when decoding a PSD image. A remote attacker can supply a specially crafted PSD image to cause a denial of service.
Other security limits still apply.
4) Out-of-bounds read (CVE-ID: CVE-2026-45359)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to disclose sensitive information and cause a denial of service.
The vulnerability exists due to out-of-bounds read in the connected components operation when processing an invalid connected-components:keep-top define value. A remote attacker can supply a crafted connected-components:keep-top value to disclose sensitive information and cause a denial of service.
5) Out-of-bounds read (CVE-ID: CVE-2026-45624)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to disclose sensitive information and cause a denial of service.
The vulnerability exists due to out-of-bounds read in the distort operation when performing a polynomial distortion with specific arguments. A remote attacker can supply specific arguments to disclose sensitive information and cause a denial of service.
6) Resource exhaustion (CVE-ID: CVE-2026-45664)
CWE-ID: CWE-400 - Resource exhaustion
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 uncontrolled resource consumption in the MNG decoder when processing crafted MNG images. A remote attacker can supply input that causes the decoder to read more images than the list limit policy allows to cause a denial of service.
7) Stack-based buffer overflow (CVE-ID: CVE-2026-46557)
CWE-ID: CWE-121 - Stack-based buffer overflow
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 a boundary error in fx operation. A local attacker can trigger stack-based buffer overflow and cause a denial of service condition on the target system.
8) Heap-based buffer overflow (CVE-ID: CVE-2026-46692)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:H/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local privileged user to cause a denial of service.
The vulnerability exists due to heap-based buffer overflow in the distributed pixel cache server when handling connections to the magick -distribute-cache service. A local privileged user can connect to the service to cause a denial of service.
9) Out-of-bounds write (CVE-ID: CVE-2026-48724)
CWE-ID: CWE-787 - Out-of-bounds write
CVSSv4: CVSS:4.0/AV:L/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 write in the Floyd-Steinberg depth dithering functionality when processing a crafted image with a mask. A remote attacker can trick the victim into opening a crafted image to cause a denial of service.
User interaction is required to open or process a crafted image.
10) Uncontrolled Recursion (CVE-ID: CVE-2026-48734)
CWE-ID: CWE-674 - Uncontrolled Recursion
CVSSv4: CVSS:4.0/AV:L/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 uncontrolled recursion in the MVG decoder when parsing a crafted MVG file. A remote attacker can trick the victim into opening a crafted file to cause a denial of service.
User interaction is required to open a crafted file.
