The BN_mod_sqrt() function, which computes a modular square root, contains a bug that can cause it to loop forever for non-prime moduli. Internally this function is used when parsing certificates that contain elliptic curve public keys in compressed form or explicit elliptic curve parameters with a base point encoded in compressed form. It is possible to trigger the infinite loop by crafting a certificate that has invalid explicit curve parameters. Since certificate parsing happens prior to verification of the certificate signature, any process that parses an externally supplied certificate may thus be subject to a denial of service attack. The infinite loop can also be reached when parsing crafted private keys as they can contain explicit elliptic curve parameters. • https://github.com/drago-96/CVE-2022-0778 https://github.com/jkakavas/CVE-2022-0778-POC https://github.com/0xUhaw/CVE-2022-0778 https://github.com/jeongjunsoo/CVE-2022-0778 http://packetstormsecurity.com/files/167344/OpenSSL-1.0.2-1.1.1-3.0-BN_mod_sqrt-Infinite-Loop.html http://seclists.org/fulldisclosure/2022/May/33 http://seclists.org/fulldisclosure/2022/May/35 http://seclists.org/fulldisclosure/2022/May/38 https://cert-portal.siemens.com/productcert/pdf/ssa-712 • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

valid.c in libxml2 before 2.9.13 has a use-after-free of ID and IDREF attributes. El archivo valid.c en libxml2 versiones anteriores a 2.9.13, presenta un uso de memoria previamente liberada de los atributos ID e IDREF. A flaw was found in libxml2. A call to the xmlGetID function can return a pointer already freed when parsing an XML document with the XML_PARSE_DTDVALID option and without the XML_PARSE_NOENT option, resulting in a use-after-free issue. • http://seclists.org/fulldisclosure/2022/May/33 http://seclists.org/fulldisclosure/2022/May/34 http://seclists.org/fulldisclosure/2022/May/35 http://seclists.org/fulldisclosure/2022/May/36 http://seclists.org/fulldisclosure/2022/May/37 http://seclists.org/fulldisclosure/2022/May/38 https://github.com/GNOME/libxml2/commit/652dd12a858989b14eed4e84e453059cd3ba340e https://gitlab.gnome.org/GNOME/libxml2/-/blob/v2.9.13/NEWS https://lists.debian.org/debian-lts-announce/2022/04/msg00004. • CWE-416: Use After Free •

Expat (aka libexpat) before 2.4.4 has a signed integer overflow in XML_GetBuffer, for configurations with a nonzero XML_CONTEXT_BYTES. Expat (también se conoce como libexpat) versiones anteriores a 2.4.4, presenta un desbordamiento de enteros con signo en la función XML_GetBuffer, para configuraciones con un XML_CONTEXT_BYTES no nulo expat (libexpat) is susceptible to a software flaw that causes process interruption. When processing a large number of prefixed XML attributes on a single tag can libexpat can terminate unexpectedly due to integer overflow. The highest threat from this vulnerability is to availability, confidentiality and integrity. • https://cert-portal.siemens.com/productcert/pdf/ssa-484086.pdf https://github.com/libexpat/libexpat/pull/550 https://lists.debian.org/debian-lts-announce/2022/03/msg00007.html https://security.gentoo.org/glsa/202209-24 https://security.netapp.com/advisory/ntap-20220217-0001 https://www.debian.org/security/2022/dsa-5073 https://www.oracle.com/security-alerts/cpuapr2022.html https://www.tenable.com/security/tns-2022-05 https://access.redhat.com/security/cve/CVE-2022-23852 https& • CWE-190: Integer Overflow or Wraparound •
