Echo: libsoup3: security update to 3.8.0-1

medium Tenable Self-Hosted Container Security Plugin ID 478252

Description

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

 - A heap buffer over-read vulnerability was discovered in libsoup's (versions: libsoup 3.0 to 3.7.0) HTTP/2
 connection tracking framework. When the library processes an HTTP/2 GOAWAY frame, it improperly handles
 the "Additional Debug Data" payload by assuming the data stream is a safely NUL-terminated C-string.
 Because the parser lacks strict length-boundary verification before reading this data, a remote,
 unauthenticated attacker can intentionally send a malformed GOAWAY frame missing the appropriate null
 delimiter. This causes the library to read past the end of the allocated buffer, triggering an application
 crash that results in a denial of service (DoS), or potentially exposing fragments of memory contents.
 (CVE-2026-15712)

Solution

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