Synopsis

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

Description

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:0010-1 advisory.

 - CVE-2025-67724: unescaped `reason` argument used in HTTP headers and in HTML default error pages can be used by attackers to launch header injection or XSS attacks (bsc#1254903).
 - CVE-2025-67725: quadratic complexity of string concatenation operations used by the `HTTPHeaders.add` method can lead to DoS when processing a maliciously crafted HTTP request (bsc#1254905).
 - CVE-2025-67726: quadratic complexity algorithm used in the `_parseparam` function of `httputil.py` can lead to DoS when processing maliciously crafted parameters in a `Content-Disposition` header (bsc#1254904).

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