Libexpat: expat: improper restriction of xml entity expansion depth in libexpat

A stack overflow vulnerability exists in the libexpat library due to the way it handles recursive entity expansion in XML documents. When parsing an XML document with deeply nested entity references, libexpat can be forced to recurse indefinitely, exhausting the stack space and causing a crash. This issue could lead to denial of service (DoS) or, in some cases, exploitable memory corruption, depending on the environment and library usage.

Qemu: denial of service via improper synchronization in qemu nbd server during socket closure

A flaw was found in the QEMU NBD Server. This vulnerability allows a denial of service (DoS) attack via improper synchronization during socket closure when a client keeps a socket open as the server is taken offline.

An integer overflow was addressed with improved input validation. This issue is fixed in iOS 26.7 and iPadOS 26.7, iOS 27.2 and iPadOS 27.2, macOS Golden Gate 27.2, macOS Sequoia 15.8.2, macOS Tahoe 26.7.2, visionOS 27.2. Processing a maliciously crafted 3D model may lead to memory corruption.

Gnutls: vulnerability in gnutls certtool template parsing

A heap-buffer-overflow (off-by-one) flaw was found in the GnuTLS software in the template parsing logic within the certtool utility. When it reads certain settings from a template file, it allows an attacker to cause an out-of-bounds (OOB) NULL pointer write, resulting in memory corruption and a denial-of-service (DoS) that could potentially crash the system.

Gnutls: vulnerability in gnutls sct extension parsing

A heap-buffer-overread vulnerability was found in GnuTLS in how it handles the Certificate Transparency (CT) Signed Certificate Timestamp (SCT) extension during X.509 certificate parsing. This flaw allows a malicious user to create a certificate containing a malformed SCT extension (OID 1.3.6.1.4.1.11129.2.4.2) that contains sensitive data. This issue leads to the exposure of confidential information when GnuTLS verifies certificates from certain websites when the certificate (SCT) is not checked correctly.

Gnutls: vulnerability in gnutls othername san export

A flaw was found in GnuTLS. A double-free vulnerability exists in GnuTLS due to incorrect ownership handling in the export logic of Subject Alternative Name (SAN) entries containing an otherName. If the type-id OID is invalid or malformed, GnuTLS will call asn1_delete_structure() on an ASN.1 node it does not own, leading to a double-free condition when the parent function or caller later attempts to free the same structure. This vulnerability can be triggered using only public GnuTLS APIs and may result in denial of service or memory corruption, depending on allocator behavior.

Libsoup: oob read on libsoup through function "soup_multipart_new_from_message" in soup-multipart.c leads to crash or exit of process

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.

Libsoup: null pointer dereference in client when server omits the "nonce" parameter in an unauthorized response with digest authentication

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.

Libsoup: denial of service in server when client requests a large amount of overlapping ranges with range header

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. This does not allow for a full denial of service.

Libsoup: null pointer deference on libsoup via /auth/soup-auth-digest.c through "soup_auth_digest_authenticate" on client when server omits the "realm" parameter in an unauthorized response with digest authentication

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.

Libsoup: null pointer dereference on libsoup through function "sniff_mp4" in soup-content-sniffer.c

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.

Libsoup: heap buffer overflows in sniff_feed_or_html() and skip_insignificant_space()

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.

Libsoup: heap buffer overflow in sniff_unknown()

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

Libsoup: segmentation fault when parsing malformed data uri

A flaw was found in libsoup. The libsoup soup_uri_decode_data_uri() function may crash when processing malformed data URI. This flaw allows an attacker to cause a denial of service (DoS).

Libsoup: integer overflow in append_param_quoted

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

Libsoup: denial of service attack to websocket server

A flaw was found in libsoup. The SoupWebsocketConnection may accept a large WebSocket message, which may cause libsoup to allocate memory and lead to a denial of service (DoS).

UniPAY Payment Gateway For WooCommerce < 2.4 - Unauthenticated Order Payment Forgery via Empty IPN Secret

The UniPAY Payment Gateway For WooCommerce WordPress plugin before 2.4 does not properly verify the authenticity of payment notifications, as their signature is checked against a merchant secret that is empty by default, allowing unauthenticated attackers to forge a valid notification and mark arbitrary orders as paid.

Gnuplot: gnuplot segmentation fault on x11_graphics

A flaw was found in gnuplot. The X11_graphics() function may lead to a segmentation fault and cause a system crash.

Gnuplot: gnuplot segmentation fault on canvas_text

A flaw was found in gnuplot. The CANVAS_text() function may lead to a segmentation fault and cause a system crash.

Gnuplot: gnuplot segmentation fault on xstrftime

A flaw was found in gnuplot. The xstrftime() function may lead to a segmentation fault, causing a system crash.
