Amazon Linux 2 : libsoup (ALAS-2025-2849)

high Nessus Plugin ID 235877

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of libsoup installed on the remote host is prior to 2.56.0-6. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2025-2849 advisory.

 A flaw was found in libsoup, where the soup_headers_parse_request() function may be vulnerable to an out- of-bound read. This flaw allows a malicious user to use a specially crafted HTTP request to crash the HTTP server. (CVE-2025-32906)

 A flaw was found in libsoup. The implementation of HTTP range requests is vulnerable to a resource consumption attack. This flaw allows a malicious client to request the same range many times in a single HTTP request, causing the server to use large amounts of memory. (CVE-2025-32907)

 libsoup: Double free on soup_message_headers_get_content_disposition() through soup-message-headers.c via params GHashTable value (CVE-2025-32911)

 A flaw was found in libsoup, where the soup_message_headers_get_content_disposition() function is vulnerable to a NULL pointer dereference. This flaw allows a malicious HTTP peer to crash a libsoup client or server that uses this function. (CVE-2025-32913)

 A flaw was found in libsoup, where the soup_multipart_new_from_message() function is vulnerable to an out- of-bounds read. This flaw allows a malicious HTTP client to induce the libsoup server to read out of bounds. (CVE-2025-32914)

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 'yum update libsoup' to update your system.
