https://notcve.org/view.php?id=CVE-2021-30860
An integer overflow was addressed with improved input validation. This issue is fixed in Security Update 2021-005 Catalina, iOS 14.8 and iPadOS 14.8, macOS Big Sur 11.6, watchOS 7.6.2. Processing a maliciously crafted PDF may lead to arbitrary code execution. Apple is aware of a report that this issue may have been actively exploited. Se ha solucionado un desbordamiento de enteros con una validación de entrada mejorada. • https://github.com/jeffssh/CVE-2021-30860 https://github.com/Levilutz/CVE-2021-30860 http://seclists.org/fulldisclosure/2021/Sep/25 http://seclists.org/fulldisclosure/2021/Sep/26 http://seclists.org/fulldisclosure/2021/Sep/27 http://seclists.org/fulldisclosure/2021/Sep/28 http://seclists.org/fulldisclosure/2021/Sep/38 http://seclists.org/fulldisclosure/2021/Sep/39 http://seclists.org/fulldisclosure/2021/Sep/40 http://seclists.org/fulldisclosure/2021/Sep/50 http://ww • CWE-190: Integer Overflow or Wraparound •

A use-after-free flaw was found in D-Bus Development branch <= 1.13.16, dbus-1.12.x stable branch <= 1.12.18, and dbus-1.10.x and older branches <= 1.10.30 when a system has multiple usernames sharing the same UID. When a set of policy rules references these usernames, D-Bus may free some memory in the heap, which is still used by data structures necessary for the other usernames sharing the UID, possibly leading to a crash or other undefined behaviors Se encontró un fallo de uso de la memoria previamente liberada D-Bus rama de desarrollo versiones iguales o anteriores a 1.13.16, dbus-1.12.x rama estable versiones iguales o anteriores a 1.12.18, y dbus-1.10.x y ramas anteriores versiones iguales o anteriores a 1.10.30 cuando un sistema tiene múltiples nombres de usuario que comparten el mismo UID. Cuando un conjunto de reglas de política hace referencia a estos nombres de usuario, D-Bus puede liberar algo de memoria en la pila, que sigue siendo utilizada por las estructuras de datos necesarias para los otros nombres de usuario que comparten el UID, lo que puede provocar un fallo u otros comportamientos indefinidos • https://bugs.gentoo.org/755392 https://bugzilla.redhat.com/show_bug.cgi?id=1909101 https://gitlab.freedesktop.org/dbus/dbus/-/issues/305#note_829128 https://security-tracker.debian.org/tracker/CVE-2020-35512 • CWE-416: Use After Free •

DCTStream::getChars in DCTStream.cc in Poppler 20.12.1 has a heap-based buffer overflow via a crafted PDF document. NOTE: later reports indicate that this only affects builds from Poppler git clones in late December 2020, not the 20.12.1 release. In this situation, it should NOT be considered a Poppler vulnerability. However, several third-party Open Source projects directly rely on Poppler git clones made at arbitrary times, and therefore the CVE remains useful to users of those projects ** EN DISPUTA ** La función DCTStream::getChars en el archivo DCTStream.cc en Poppler versión 20.12.1, presenta un desbordamiento del búfer en la región stack de la memoria por medio de un documento PDF diseñado. NOTA: informes posteriores indican que esto sólo afecta a las construcciones de los clones de git de Poppler a finales de diciembre de 2020, no a la versión 20.12.1. • https://gitlab.freedesktop.org/poppler/poppler/-/issues/1011 • CWE-787: Out-of-bounds Write •

A flaw was found in the xdg-email component of xdg-utils-1.1.0-rc1 and newer. When handling mailto: URIs, xdg-email allows attachments to be discreetly added via the URI when being passed to Thunderbird. An attacker could potentially send a victim a URI that automatically attaches a sensitive file to a new email. If a victim user does not notice that an attachment was added and sends the email, this could result in sensitive information disclosure. It has been confirmed that the code behind this issue is in xdg-email and not in Thunderbird. • https://bugzilla.redhat.com/show_bug.cgi?id=1899769 https://gitlab.freedesktop.org/xdg/xdg-utils/-/issues/177 • CWE-201: Insertion of Sensitive Information Into Sent Data •
