Echo: libsoup3: security update to 3.8.0-1

medium Tenable Cloud Security Plugin ID 478242

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - An out-of-bounds read vulnerability was found in libsoup's multipart processing subsystem. The flaw exists
 in the soup_multipart_input_stream_read_headers() function inside soup-multipart-input-stream.c, which
 does not adequately restrict or validate the size of incoming multipart boundary strings. When processing
 a crafted HTTP response containing a malformed or oversized boundary parameter, the internal stream reader
 reads past the allocated buffer bounds. A remote, unauthenticated attacker can exploit this behavior to
 cause a service denial (DoS) through application failure or potentially read fragments of unauthorized
 memory metadata. (CVE-2026-15714)

Solution

Update the libsoup3 library and its related packages to version 3.8.0-1 or later.
