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

The vulnerability exists due to use-after-free in the ImagesToBlob method when processing images. A remote attacker can trigger the use-after-free condition to cause a denial of service.


2) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2026-93587)

CWE-ID: CWE-770 - Allocation of Resources Without Limits or Throttling

CVSSv4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to allocation of resources without limits or throttling in the PCD decoder when providing a specific command-line option. A local user can provide the specific command-line option to cause extra memory allocation and cause a denial of service.


3) NULL pointer dereference (CVE-ID: CVE-2026-93588)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: 2.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]


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

The vulnerability exists due to null pointer dereference in the PNM coder when hitting a memory limit. A remote user can cause the PNM coder to hit a memory limit to cause a denial of service.


4) Division by zero (CVE-ID: CVE-2026-93589)

CWE-ID: CWE-369 - Divide By Zero

CVSSv4: 6.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]


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

The vulnerability exists due to division by zero in the FLIF encoder when processing an incorrect ticks-per-second value. A remote attacker can provide an incorrect ticks-per-second value to cause a denial of service.


5) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2026-93590)

CWE-ID: CWE-770 - Allocation of Resources Without Limits or Throttling

CVSSv4: 6.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]


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 UHDR encoder when allocating a buffer that contains all the pixels of an image. A remote attacker can cause the encoder to allocate a buffer containing all the pixels of an image to cause a denial of service.


6) Out-of-bounds write (CVE-ID: CVE-2026-106571)

CWE-ID: CWE-787 - Out-of-bounds write

CVSSv4: 5.7 [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]


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

The vulnerability exists due to an out-of-bounds write in the GetVirtualPixels API when processing a crafted API call. A remote attacker can make a crafted call to the GetVirtualPixels API to cause a denial of service.


7) Resource exhaustion (CVE-ID: CVE-2026-106573)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: 6.9 [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]


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

The vulnerability exists due to uncontrolled resource consumption in the MVG decoder when processing a crafted image. A remote attacker can submit a crafted image that triggers a long-running operation to cause a denial of service.


8) Missing Release of File Descriptor or Handle after Effective Lifetime (CVE-ID: CVE-2026-106575)

CWE-ID: CWE-775 - Missing Release of File Descriptor or Handle after Effective Lifetime

CVSSv4: 6.9 [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]


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

The vulnerability exists due to missing release of a file descriptor or handle after effective lifetime in magick script processing when processing a crafted magick script. A remote attacker can provide a crafted magick script to cause a denial of service.


9) Heap-based buffer overflow (CVE-ID: CVE-2026-106574)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: 6 [CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


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

The vulnerability exists due to a heap-based buffer overflow in the distributed pixel cache server when processing data sent by a client. A remote attacker can send crafted data to cause a denial of service.


10) Excessive Iteration (CVE-ID: CVE-2026-106576)

CWE-ID: CWE-834 - Excessive Iteration

CVSSv4: 6.9 [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]


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

The vulnerability exists due to excessive iteration in the XMP profile parser when determining the numerator and denominator from a crafted XMP profile. A remote attacker can supply a crafted XMP profile to cause a denial of service.


11) Improper access control (CVE-ID: CVE-2026-106579)

CWE-ID: CWE-284 - Improper Access Control

CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to disclose sensitive information.

The vulnerability exists due to improper access control in ImageMagick policy handling when processing a crafted image under a policy that uses coder as the domain. A remote attacker can process a crafted image to disclose sensitive information.

Default policies use the module domain.


12) Code Injection (CVE-ID: CVE-2026-106577)

CWE-ID: CWE-94 - Improper Control of Generation of Code ('Code Injection')

CVSSv4: 5.6 [CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to inject code.

The vulnerability exists due to improper neutralization of special elements in the postscript coders when processing crafted input. A remote attacker can provide crafted values to inject code.

User interaction is required.
