Description

This security bulletin contains information about 5 vulnerabilities.


1) Use-after-free (CVE-ID: N/A)

CWE-ID: CWE-416 - Use After Free

CVSSv4: 2 [CVSS:4.0/AV:L/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 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: N/A)

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: N/A)

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: N/A)

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: N/A)

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.
