Description

This security bulletin contains information about 6 vulnerabilities.


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

CWE-ID: CWE-416 - Use After Free

CVSSv4: 4.6 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in Layer method of PerlMagick. A remote attacker can use a specially crafted list of images and cause a denial of service (DoS) condition.


2) Resource exhaustion (CVE-ID: N/A)

CWE-ID: CWE-400 - Resource exhaustion

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 perform a denial of service (DoS) attack.

The vulnerability exists due to application does not properly control consumption of internal resources in OpenPixelCache. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


3) Memory leak (CVE-ID: N/A)

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

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 perform DoS attack on the target system.

The vulnerability exists due memory leak in MSL decoder. A remote attacker can use a specially crafted MSL image and perform denial of service attack.


4) Link following (CVE-ID: N/A)

CWE-ID: CWE-59 - Improper Link Resolution Before File Access ('Link Following')

CVSSv4: 1 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a local user to compromise the target system.

The vulnerability exists due to time-of-check time-of-use race condition. A local user can bypass policy-denied read or write on Windows.


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

CWE-ID: CWE-416 - Use After Free

CVSSv4: 4.6 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in the GetList method of PerlMagick. A remote attacker can use a specially crafted call and cause a denial of service (DoS) condition.


6) Time-of-check Time-of-use (TOCTOU) Race Condition (CVE-ID: N/A)

CWE-ID: CWE-367 - Time-of-check Time-of-use (TOCTOU) Race Condition

CVSSv4: 2 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a local user to compromise the target system.

The vulnerability exists due to time-of-check time-of-use race condition in the video decoder. A local user can bypass policy-denied write in the video decoder.
