CVSS: 7.5EPSS: 2%CPEs: 32EXPL: 4CVE-2022-0778 – Infinite loop in BN_mod_sqrt() reachable when parsing certificates
https://notcve.org/view.php?id=CVE-2022-0778
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') •
CVSS: 7.5EPSS: 1%CPEs: 9EXPL: 0CVE-2022-23990 – expat: integer overflow in the doProlog function
https://notcve.org/view.php?id=CVE-2022-23990
Expat (aka libexpat) before 2.4.4 has an integer overflow in the doProlog function. Expat (también se conoce como libexpat) versiones anteriores a 2.4.4, presenta un desbordamiento de enteros en la función doProlog A flaw was found in expat. The vulnerability occurs due to large content in element type declarations when there is an element declaration handler present which leads to an integer overflow. This flaw allows an attacker to inject an unsigned integer, leading to a crash or a denial of service. • https://cert-portal.siemens.com/productcert/pdf/ssa-484086.pdf https://github.com/libexpat/libexpat/pull/551 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/34NXVL2RZC2YZRV74ZQ3RNFB7WCEUP7D https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/R7FF2UH7MPXKTADYSJUAHI2Y5UHBSHUH https://security.gentoo.org/glsa/202209-24 https://www.debian.org/security/2022/dsa-5073 https://www.oracle.com/security-alerts/cpuapr2022.html https://www. • CWE-190: Integer Overflow or Wraparound •
