Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS / 24.04 LTS / 24.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7418-1 advisory.

 It was discovered that Ruby incorrectly handled parsing of an XML document that has specific XML characters in an attribute value using REXML gem. An attacker could use this issue to cause Ruby to crash, resulting in a denial of service. This issue only affected in Ubuntu 22.04 LTS, Ubuntu 24.04 LTS, and Ubuntu 24.10. (CVE-2024-35176, CVE-2024-39908, CVE-2024-41123, CVE-2024-43398)

 It was discovered that Ruby incorrectly handled expanding ranges in the net-imap response parser. If a user or automated system were tricked into connecting to a malicious IMAP server, a remote attacker could possibly use this issue to consume memory, leading to a denial of service. This issue only affected Ubuntu 24.04 LTS, and Ubuntu 24.10. (CVE-2025-25186)

 It was discovered that the Ruby CGI gem incorrectly handled parsing certain cookies. A remote attacker could possibly use this issue to consume resources, leading to a denial of service. (CVE-2025-27219)

 It was discovered that the Ruby CGI gem incorrectly handled parsing certain regular expressions. A remote attacker could possibly use this issue to consume resources, leading to a denial of service.
 (CVE-2025-27220)

 It was discovered that the Ruby URI gem incorrectly handled certain URI handling methods. A remote attacker could possibly use this issue to leak authentication credentials. (CVE-2025-27221)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
