CVSS: 7.5EPSS: 0%CPEs: 43EXPL: 0CVE-2022-1473 – Resource leakage when decoding certificates and keys
https://notcve.org/view.php?id=CVE-2022-1473
The OPENSSL_LH_flush() function, which empties a hash table, contains a bug that breaks reuse of the memory occuppied by the removed hash table entries. This function is used when decoding certificates or keys. If a long lived process periodically decodes certificates or keys its memory usage will expand without bounds and the process might be terminated by the operating system causing a denial of service. Also traversing the empty hash table entries will take increasingly more time. Typically such long lived processes might be TLS clients or TLS servers configured to accept client certificate authentication. • https://cert-portal.siemens.com/productcert/pdf/ssa-953464.pdf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=64c85430f95200b6b51fe9475bd5203f7c19daf1 https://security.gentoo.org/glsa/202210-02 https://security.netapp.com/advisory/ntap-20220602-0009 https://www.openssl.org/news/secadv/20220503.txt https://access.redhat.com/security/cve/CVE-2022-1473 https://bugzilla.redhat.com/show_bug.cgi?id=2087913 • CWE-401: Missing Release of Memory after Effective Lifetime CWE-459: Incomplete Cleanup •
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 •
