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-2019-18197
In xsltCopyText in transform.c in libxslt 1.1.33, a pointer variable isn't reset under certain circumstances. If the relevant memory area happened to be freed and reused in a certain way, a bounds check could fail and memory outside a buffer could be written to, or uninitialized data could be disclosed. En la función xsltCopyText en el archivo transform.c en libxslt versión 1.1.33, una variable de puntero no se restablece bajo determinadas circunstancias. Si el área de memoria relevante se liberó y reutilizó de cierta manera, una comprobación de límites podría fallar y podría escribirse la memoria fuera de un búfer o podrían divulgarse datos no inicializados. • http://lists.opensuse.org/opensuse-security-announce/2020-02/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2020-02/msg00015.html http://lists.opensuse.org/opensuse-security-announce/2020-02/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00062.html http://www.openwall.com/lists/oss-security/2019/11/17/2 https://access.redhat.com/errata/RHSA-2020:0514 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=15746 https://bugs.chromium.or • CWE-416: Use After Free CWE-908: Use of Uninitialized Resource •
