Description

This security bulletin contains information about 2 vulnerabilities.


1) Time-of-check Time-of-use (TOCTOU) Race Condition (CVE-ID: CVE-2025-47290)

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

CVSSv4: CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to a race condition while unpacking an image during an image pull. A remote attacker can trick the victim into using a specially crafted image and perform arbitrary modifications of the host file system, leading to its compromise.


2) Input validation error (CVE-ID: CVE-2025-22872)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to perform code injection attacks.

The vulnerability exists due to insufficient validation of tags with unquoted attribute values that end with a solidus character (/). The tokenizer can interpret such tags as self-closing, leading to content following such tags as being placed in the wrong scope during DOM construction.
