CVSS: 7.4EPSS: 0%CPEs: 28EXPL: 2CVE-2022-29824 – libxml2: integer overflows in xmlBuf and xmlBuffer lead to out-of-bounds write
https://notcve.org/view.php?id=CVE-2022-29824
In libxml2 before 2.9.14, several buffer handling functions in buf.c (xmlBuf*) and tree.c (xmlBuffer*) don't check for integer overflows. This can result in out-of-bounds memory writes. Exploitation requires a victim to open a crafted, multi-gigabyte XML file. Other software using libxml2's buffer functions, for example libxslt through 1.1.35, is affected as well. En libxml2 versiones anteriores a 2.9.14, varias funciones de manejo de búferes en buf.c (xmlBuf*) y tree.c (xmlBuffer*) no comprueban los desbordamientos de enteros. • http://packetstormsecurity.com/files/167345/libxml2-xmlBufAdd-Heap-Buffer-Overflow.html http://packetstormsecurity.com/files/169825/libxml2-xmlParseNameComplex-Integer-Overflow.html https://gitlab.gnome.org/GNOME/libxml2/-/commit/2554a2408e09f13652049e5ffb0d26196b02ebab https://gitlab.gnome.org/GNOME/libxml2/-/commit/6c283d83eccd940bcde15634ac8c7f100e3caefd https://gitlab.gnome.org/GNOME/libxml2/-/tags/v2.9.14 https://gitlab.gnome.org/GNOME/libxslt/-/tags https://lists.debian.org/debian-lts-announce/2022/05/msg0 • CWE-190: Integer Overflow or Wraparound CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2019-11068
libxslt through 1.1.33 allows bypass of a protection mechanism because callers of xsltCheckRead and xsltCheckWrite permit access even upon receiving a -1 error code. xsltCheckRead can return -1 for a crafted URL that is not actually invalid and is subsequently loaded. libxslt hasta la versión 1.1.33 permite omitir los mecanismos de protección debido a que los callers xsltCheckRead y xsltCheckWrite permiten acceso incluso después de recibir el código de error -1. xsltCheckRead puede devolver -1 para una URL creada que no es realmente inválida y que se carga posteriormente. • http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00048.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00052.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00053.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00001.html http://www.openwall.com/lists/oss-security/2019/04/22/1 http://www.openwall.com/lists/oss-security/2019/04/23/5 https • CWE-284: Improper Access Control •
