Affected: AlmaLinux:8: libsoup, AlmaLinux:8: libsoup-devel

The libsoup packages provide an HTTP client and server library for GNOME.

Security Fix(es):

* libsoup: Integer overflow in append_param_quoted (CVE-2025-32050) * libsoup: Heap buffer overflow in sniff_unknown() (CVE-2025-32052) * libsoup: Heap buffer overflows in sniff_feed_or_html() and skip_insignificant_space() (CVE-2025-32053) * libsoup: Out of bounds reads in soup_headers_parse_request() (CVE-2025-32906) * libsoup: Double free on soup_message_headers_get_content_disposition() through "soup-message-headers.c" via "params" GHashTable value (CVE-2025-32911) * libsoup: NULL pointer dereference in soup_message_headers_get_content_disposition when "filename" parameter is present, but has no value in Content-Disposition header (CVE-2025-32913) * libsoup: Information disclosure may leads libsoup client sends Authorization header to a different host when being redirected by a server (CVE-2025-46421) * libsoup: Memory leak on soup_header_parse_quality_list() via soup-headers.c (CVE-2025-46420)

libsoup is an HTTP client/server library for GNOME. It uses GObjects and the glib main loop, to integrate well with GNOME applications, and also has a synchronous API, for use in threaded applications. Security Fix(es):

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. 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)

A flaw was found in libsoup, where SoupAuthDigest is vulnerable to a NULL pointer dereference. The HTTP server may cause the libsoup client to crash.(CVE-2025-32912)

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 th…
