CVSS: 5.9EPSS: 0%CPEs: 205EXPL: 0CVE-2021-3449 – NULL pointer deref in signature_algorithms processing
https://notcve.org/view.php?id=CVE-2021-3449
An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was present in the initial ClientHello), but includes a signature_algorithms_cert extension then a NULL pointer dereference will result, leading to a crash and a denial of service attack. A server is only vulnerable if it has TLSv1.2 and renegotiation enabled (which is the default configuration). OpenSSL TLS clients are not impacted by this issue. All OpenSSL 1.1.1 versions are affected by this issue. • http://www.openwall.com/lists/oss-security/2021/03/27/1 http://www.openwall.com/lists/oss-security/2021/03/27/2 http://www.openwall.com/lists/oss-security/2021/03/28/3 http://www.openwall.com/lists/oss-security/2021/03/28/4 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://cert-portal.siemens.com/productcert/pdf/ssa-772220.pdf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=fb9fa6b51defd48157eeb207f52181f735d96148 https://kb.pulse • CWE-476: NULL Pointer Dereference •

OpenSSL 0.9.6 before 0.9.6d does not properly handle unknown message types, which allows remote attackers to cause a denial of service (infinite loop), as demonstrated using the Codenomicon TLS Test Tool. OpenSSL 0.9.6 anteriores a la 0.9.6d no manejan adecuadamente los tipos de mensajes desconocidos, lo que permite a atacantes remotos causar una denegación de servicios (por bucle infinito), como se demuestra utilizando la herramienta de testeo Codenomicon TLS. • ftp://ftp.sco.com/pub/updates/OpenServer/SCOSA-2004.10/SCOSA-2004.10.txt ftp://patches.sgi.com/support/free/security/advisories/20040304-01-U.asc http://distro.conectiva.com.br/atualizacoes/?id=a&anuncio=000834 http://fedoranews.org/updates/FEDORA-2004-095.shtml http://marc.info/?l=bugtraq&m=107955049331965&w=2 http://marc.info/?l=bugtraq&m=108403850228012&w=2 http://rhn.redhat.com/errata/RHSA-2004-119.html http://secunia.com/advisories/11139 http://security.gen •

The SSL/TLS handshaking code in OpenSSL 0.9.7a, 0.9.7b, and 0.9.7c, when using Kerberos ciphersuites, does not properly check the length of Kerberos tickets during a handshake, which allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that causes an out-of-bounds read. El código que une SSL/TLS en OpenSSL 0.9.7a, 0.9.7b y 0.9.7c, usando Kerberos, no comprueba adecuadamente la longitud de los tickets de Kerberos, lo que permite que atacantes remotos provoquen una denegación de servicio. • ftp://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2004-005.txt.asc ftp://ftp.sco.com/pub/updates/OpenServer/SCOSA-2004.10/SCOSA-2004.10.txt http://distro.conectiva.com.br/atualizacoes/?id=a&anuncio=000834 http://docs.info.apple.com/article.html?artnum=61798 http://lists.apple.com/archives/security-announce/2005//Aug/msg00001.html http://lists.apple.com/archives/security-announce/2005/Aug/msg00000.html http://lists.apple.com/mhonarc/security-announce/msg00045.html http: • CWE-125: Out-of-bounds Read •
