medium Nessus Plugin ID 299528

Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1439 advisory.

A flaw was found in libsoup. The libsoup append_param_quoted() function may contain an overflow bug resulting in a buffer under-read. (CVE-2025-32050)

A flaw was found in libsoup. A vulnerability in the sniff_unknown() function may lead to heap buffer over- read. (CVE-2025-32052)

A flaw was found in libsoup. A vulnerability in sniff_feed_or_html() and skip_insignificant_space() functions may lead to a heap buffer over-read. (CVE-2025-32053)

A flaw was found in libsoup. SoupContentSniffer may be vulnerable to a NULL pointer dereference in the sniff_mp4 function. The HTTP server may cause the libsoup client to crash. (CVE-2025-32909)

A flaw was found in libsoup, where soup_auth_digest_authenticate() is vulnerable to a NULL pointer dereference. This issue may cause the libsoup client to crash. (CVE-2025-32910)

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

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

Solution

Run 'dnf update libsoup --releasever 2023.10.20260216' or or 'dnf update --advisory ALAS2023-2026-1439 --releasever 2023.10.20260216' to update your system.
