Description

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS / 25.04 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7643-1 advisory.

 Jan Raski discovered that libsoup incorrectly handled range headers in an HTTP request. An attacker could possibly use this issue to cause libsoup to consume excessive memory, resulting in a denial of service. (CVE-2025-32907)

 Alon Zahavi discovered that libsoup incorrectly handled memory when parsing HTTP requests. An attacker could possibly use this issue to send a maliciously crafted HTTP request to the server, causing a denial of service or obtaining sensitive information. This issue only affected Ubuntu 25.04. (CVE-2025-32914)

 It was discovered that libsoup incorrectly handled memory when parsing the expiration date of maliciously crafted cookies. An attacker could possibly use this issue to cause a denial of service. (CVE-2025-4945)

 It was discovered that libsoup incorrectly handled integer calculations when parsing multipart data. An attacker could possibly use this issue to cause a denial of service. (CVE-2025-4948)
