Invalid pointer in the JavaScript Engine: JIT component. This vulnerability was fixed in Firefox 157.

Release of invalid pointer or reference in Windows Device Association Service allows an authorized attacker to elevate privileges locally.

Se ha identificado un fallo en libxml2 (cuando está compilado con bindings de Python) que permite a atacantes remotos provocar una denegación de servicio mediante documentos XML especialmente diseñados con Definiciones de Tipo de Documento (DTD) que contienen valores de atributos enumerados. La vulnerabilidad explota un error de doble liberación de memoria en el manejador de retrollamada SAX attributeDecl, afectando potencialmente servidores web, APIs y aplicaciones que procesan XML en entornos LATAM.

Privilege escalation due to invalid pointer in the Graphics component. This vulnerability was fixed in Firefox 154 and Firefox ESR 153.1.

When the application opens a PDF file and JavaScript writes annotation attributes, there is a lack of sufficient object type and argument checks. As a result, due to the damage to the internal structure of the annotations, it causes the application to crash during subsequent release.

In the Linux kernel, the following vulnerability has been resolved: netfilter: nat: use kfree_rcu to release ops Florian Westphal says: "Historically this is not an issue, even for normal base hooks: the data path doesn't use the original nf_hook_ops that are used to register the callbacks. However, in v5.14 I added the ability to dump the active netfilter hooks from userspace. This code will…

In the Linux kernel, the following vulnerability has been resolved: tipc: fix double-free in tipc_buf_append() tipc_msg_validate() can potentially reallocate the skb it is validating, freeing the old one. In tipc_buf_append(), it was being called with a pointer to a local variable which was a copy of the caller's skb pointer. If the skb was reallocated and validation subsequently failed, the e…

Cpanel::JSON::XS versions before 4.41 for Perl allow denial of service via UTF-8 BOM prefixed input when a decode filter callback throws. To skip a leading 3-byte UTF-8 BOM, decode_json() advances the input scalar's string pointer past the mark with SvPV_set() and restores it only on the normal return path. When decoding aborts through a Perl exception, for example a filter_json_object callback t…
