https://notcve.org/view.php?id=CVE-2022-3602
A buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking. Note that this occurs after certificate chain signature verification and requires either a CA to have signed the malicious certificate or for the application to continue certificate verification despite failure to construct a path to a trusted issuer. An attacker can craft a malicious email address to overflow four attacker-controlled bytes on the stack. This buffer overflow could result in a crash (causing a denial of service) or potentially remote code execution. Many platforms implement stack overflow protections which would mitigate against the risk of remote code execution. • https://github.com/colmmacc/CVE-2022-3602 https://github.com/eatscrayon/CVE-2022-3602-poc https://github.com/corelight/CVE-2022-3602 https://github.com/cybersecurityworks553/CVE-2022-3602-and-CVE-2022-3786 http://packetstormsecurity.com/files/169687/OpenSSL-Security-Advisory-20221101.html http://www.openwall.com/lists/oss-security/2022/11/01/15 http://www.openwall.com/lists/oss-security/2022/11/01/16 http://www.openwall.com/lists/oss-security/2022/11/01/17 http://www&# • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2022-3786
A buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking. Note that this occurs after certificate chain signature verification and requires either a CA to have signed a malicious certificate or for an application to continue certificate verification despite failure to construct a path to a trusted issuer. An attacker can craft a malicious email address in a certificate to overflow an arbitrary number of bytes containing the `.' character (decimal 46) on the stack. This buffer overflow could result in a crash (causing a denial of service). In a TLS client, this can be triggered by connecting to a malicious server. • https://github.com/cybersecurityworks553/CVE-2022-3602-and-CVE-2022-3786 https://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff;h=c42165b5706e42f67ef8ef4c351a9a4c5d21639a https://www.openssl.org/news/secadv/20221101.txt https://access.redhat.com/security/cve/CVE-2022-3786 https://bugzilla.redhat.com/show_bug.cgi?id=2139104 https://access.redhat.com/security/vulnerabilities/RHSB-2022-004 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-193: Off-by-one Error •
CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 0CVE-2022-3358 – Using a Custom Cipher with NID_undef may lead to NULL encryption
https://notcve.org/view.php?id=CVE-2022-3358
OpenSSL supports creating a custom cipher via the legacy EVP_CIPHER_meth_new() function and associated function calls. This function was deprecated in OpenSSL 3.0 and application authors are instead encouraged to use the new provider mechanism in order to implement custom ciphers. OpenSSL versions 3.0.0 to 3.0.5 incorrectly handle legacy custom ciphers passed to the EVP_EncryptInit_ex2(), EVP_DecryptInit_ex2() and EVP_CipherInit_ex2() functions (as well as other similarly named encryption and decryption initialisation functions). Instead of using the custom cipher directly it incorrectly tries to fetch an equivalent cipher from the available providers. An equivalent cipher is found based on the NID passed to EVP_CIPHER_meth_new(). • https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=5485c56679d7c49b96e8fc8ca708b0b7e7c03c4b https://psirt.global.sonicwall.com/vuln-detail/SNWLID-2022-0023 https://security.gentoo.org/glsa/202402-08 https://security.netapp.com/advisory/ntap-20221028-0014 https://www.openssl.org/news/secadv/20221011.txt https://access.redhat.com/security/cve/CVE-2022-3358 https://bugzilla.redhat.com/show_bug.cgi?id=2134740 • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2022-2097
AES OCB mode for 32-bit x86 platforms using the AES-NI assembly optimised implementation will not encrypt the entirety of the data under some circumstances. This could reveal sixteen bytes of data that was preexisting in the memory that wasn't written. In the special case of "in place" encryption, sixteen bytes of the plaintext would be revealed. Since OpenSSL does not support OCB based cipher suites for TLS and DTLS, they are both unaffected. Fixed in OpenSSL 3.0.5 (Affected 3.0.0-3.0.4). • https://cert-portal.siemens.com/productcert/pdf/ssa-332410.pdf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=919925673d6c9cfed3c1085497f5dfbbed5fc431 https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=a98f339ddd7e8f487d6e0088d4a9a42324885a93 https://lists.debian.org/debian-lts-announce/2023/02/msg00019.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/R6CK57NBQFTPUMXAPJURCGXUYT76NQAK https://lists.fedoraproject.org/archives/list/package-announce%40lists.fe • CWE-325: Missing Cryptographic Step CWE-327: Use of a Broken or Risky Cryptographic Algorithm •

https://notcve.org/view.php?id=CVE-2022-2274
The OpenSSL 3.0.4 release introduced a serious bug in the RSA implementation for X86_64 CPUs supporting the AVX512IFMA instructions. This issue makes the RSA implementation with 2048 bit private keys incorrect on such machines and memory corruption will happen during the computation. As a consequence of the memory corruption an attacker may be able to trigger a remote code execution on the machine performing the computation. SSL/TLS servers or other servers using 2048 bit RSA private keys running on machines supporting AVX512IFMA instructions of the X86_64 architecture are affected by this issue. OpenSSL versión 3.0.4, introdujo un grave error en la implementación de RSA para CPUs X86_64 que soportan las instrucciones AVX512IFMA. • https://github.com/Malwareman007/CVE-2022-2274 https://github.com/DesmondSanctity/CVE-2022-2274 https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=4d8a88c134df634ba610ff8db1eb8478ac5fd345 https://github.com/openssl/openssl/issues/18625 https://security.netapp.com/advisory/ntap-20220715-0010 https://www.openssl.org/news/secadv/20220705.txt • CWE-787: Out-of-bounds Write •
