A vulnerability was found in the libsoup package. This flaw stems from its failure to correctly verify the termination of multipart HTTP messages. This can allow a remote attacker to send a specially crafted multipart HTTP body, causing the libsoup-consuming server to read beyond its allocated memory boundaries (out-of-bounds read).

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)

    It was discovered that libsoup incorrectly handled buffer reading when locating boundaries in multipart     forms. An attacker could possibly use this issue to cause a denial of service or obtain sensitive     information. (CVE-2025-4969)
