Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) Input validation error

EUVDB-ID: #VU94361

Risk: Medium

CVSSv4.0: 7.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Green]

CVE-ID: CVE-2024-35176

CWE-ID: CWE-20 - Improper input validation

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input when parsing XML that has multiple bracket character occurrences (e.g. "<") in an attribute value. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.

Mitigation

Update the affected package ruby3.0 to the latest version.
