20 Feb 2024 — A website could have obscured the fullscreen notification by using a dropdown select input element. This could have led to user confusion and possible spoofing attacks. This vulnerability affects Firefox < 123, Firefox ESR < 115.8, and Thunderbird < 115.8. Un sitio web podría haber oscurecido la notificación de pantalla completa mediante el uso de un elemento de entrada de selección desplegable. Esto podría haber generado confusión en los usuarios y posibles ataques de suplantación de identidad. • https://bugzilla.mozilla.org/show_bug.cgi?id=1832627 • CWE-449: The UI Performs the Wrong Action •

20 Feb 2024 — When storing and re-accessing data on a networking channel, the length of buffers may have been confused, resulting in an out-of-bounds memory read. This vulnerability affects Firefox < 123, Firefox ESR < 115.8, and Thunderbird < 115.8. Al almacenar y volver a acceder a datos en un canal de red, es posible que se haya confundido la longitud de los bufferse, lo que resulta en una lectura de memoria fuera de los límites.

31 Jan 2024 — A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. The nft_verdict_init() function allows positive values as drop error within the hook verdict, and hence the nf_hook_slow() function can cause a double free vulnerability when NF_DROP is issued with a drop error which resembles NF_ACCEPT. We recommend upgrading past commit f342de4e2f33e0e39165d8639387aa6c19dff660.

17 Jan 2024 — A flaw was found in the X.Org server. The GLX PBuffer code does not call the XACE hook when creating the buffer, leaving it unlabeled. When the client issues another request to access that resource (as with a GetGeometry) or when it creates another resource that needs to access that buffer, such as a GC, the XSELINUX code will try to use an object that was never labeled and crash because the SID is NULL. Se encontró una falla en el servidor X.Org.

17 Jan 2024 — A flaw was found in the X.Org server. The cursor code in both Xephyr and Xwayland uses the wrong type of private at creation. It uses the cursor bits type with the cursor as private, and when initiating the cursor, that overwrites the XSELINUX context. Se encontró una falla en el servidor X.Org. El código del cursor tanto en Xephyr como en Xwayland utiliza el tipo incorrecto de privado en el momento de la creación. • https://access.redhat.com/errata/RHSA-2024:0320 • CWE-787: Out-of-bounds Write •

17 Jan 2024 — A flaw was found in X.Org server. Both DeviceFocusEvent and the XIQueryPointer reply contain a bit for each logical button currently down. Buttons can be arbitrarily mapped to any value up to 255, but the X.Org Server was only allocating space for the device's particular number of buttons, leading to a heap overflow if a bigger value was used. Se encontró un fallo en el servidor X.Org. Tanto DeviceFocusEvent como la respuesta de XIQueryPointer contienen un bit para cada botón lógico actualmente presionado. • http://www.openwall.com/lists/oss-security/2024/01/18/1 • CWE-787: Out-of-bounds Write •

10 Jan 2024 — A Cross-site request forgery vulnerability exists in ipa/session/login_password in all supported versions of IPA. This flaw allows an attacker to trick the user into submitting a request that could perform actions as the user, resulting in a loss of confidentiality and system integrity. During community penetration testing it was found that for certain HTTP end-points FreeIPA does not ensure CSRF protection. Due to implementation details one cannot use this flaw for reflection of a cookie representing alrea... • https://access.redhat.com/errata/RHSA-2024:0137 • CWE-352: Cross-Site Request Forgery (CSRF) •

10 Jan 2024 — NSS was susceptible to a timing side-channel attack when performing RSA decryption. This attack could potentially allow an attacker to recover the private data. This vulnerability affects Firefox < 124, Firefox ESR < 115.9, and Thunderbird < 115.9. NSS era susceptible a un ataque de canal lateral de sincronización al realizar el descifrado RSA.

15 Nov 2023 — GStreamer AV1 Codec Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GStreamer. Interaction with this library is required to exploit this vulnerability but attack vectors may vary depending on the implementation. The specific flaw exists within the parsing of AV1 encoded video files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying ... • https://gstreamer.freedesktop.org/security/sa-2023-0009.html • CWE-122: Heap-based Buffer Overflow •
