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 •
CVSS: 7.5EPSS: 0%CPEs: 67EXPL: 0CVE-2021-23840 – Integer overflow in CipherUpdate
https://notcve.org/view.php?id=CVE-2021-23840
Calls to EVP_CipherUpdate, EVP_EncryptUpdate and EVP_DecryptUpdate may overflow the output length argument in some cases where the input length is close to the maximum permissable length for an integer on the platform. In such cases the return value from the function call will be 1 (indicating success), but the output length value will be negative. This could cause applications to behave incorrectly or crash. OpenSSL versions 1.1.1i and below are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1j. • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=6a51b9e1d0cf0bf8515f7201b68fb0a3482b3dc1 https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=9b1129239f3ebb1d1c98ce9ed41d5c9476c47cb2 https://kb.pulsesecure.net/articles/Pulse_Security_Advisories/SA44846 https://kc.mcafee.com/corporate/index?page=content&id=SB10366 https://lists.apache.org/thread.html/r58af02e294bd07f487e2c64ffc0a29b837db5600e33b6e698b9d696b%40%3Cissues.bookkeeper.apache.org%3E https:/ • CWE-190: Integer Overflow or Wraparound •
CVSS: 5.9EPSS: 0%CPEs: 75EXPL: 1CVE-2020-1971 – EDIPARTYNAME NULL pointer dereference
https://notcve.org/view.php?id=CVE-2020-1971
The X.509 GeneralName type is a generic type for representing different types of names. One of those name types is known as EDIPartyName. OpenSSL provides a function GENERAL_NAME_cmp which compares different instances of a GENERAL_NAME to see if they are equal or not. This function behaves incorrectly when both GENERAL_NAMEs contain an EDIPARTYNAME. A NULL pointer dereference and a crash may occur leading to a possible denial of service attack. • https://github.com/MBHudson/CVE-2020-1971 http://www.openwall.com/lists/oss-security/2021/09/14/2 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=2154ab83e14ede338d2ede9bbe5cdfce5d5a6c9e https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=f960d81215ebf3f65e03d4d5d857fb9b666d6920 https://kb.pulsesecure.net/articles/Pulse_Security_Advisories/SA44676 https://lists.apache.org/thread.html/r63c6f2dd363d9b514d0a4bcf624580616a679898cc14c109a49b7 • CWE-476: NULL Pointer Dereference •

This problem is patched in jQuery 3.5.0. En las versiones de jQuery mayores o iguales a 1.2 y anteriores a la versión 3.5.0, se puede ejecutar HTML desde fuentes no seguras, incluso después de desinfectarlo, a uno de los métodos de manipulación DOM de jQuery (es decir .html (), .append () y otros). código no seguro Este problema está corregido en jQuery 3.5.0. A Cross-site scripting (XSS) vulnerability exists in JQuery. This flaw allows an attacker with the ability to supply input to the ‘HTML’ function to inject Javascript into the page where that input is rendered, and have it delivered by the browser. jQuery version 1.2 suffers from a cross site scripting vulnerability. • https://www.exploit-db.com/exploits/49766 https://github.com/0xAJ2K/CVE-2020-11022-CVE-2020-11023 https://github.com/ossf-cve-benchmark/CVE-2020-11022 https://github.com/Snorlyd/https-nj.gov---CVE-2020-11022 http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00067.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00085.html http://lists.opensuse.org/opensuse-security-announce/2020-11/msg00039.html http://packetstormsecurity.com/files/162159/jQuery-1.2& • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
