A buffer over-read vulnerability exists in Wibu-Systems CodeMeter versions < 7.21a. An unauthenticated remote attacker can exploit this issue to disclose heap memory contents or crash the CodeMeter Runtime Server. Se presenta una vulnerabilidad de lectura excesiva del búfer en Wibu-Systems CodeMeter versiones anteriores a 7.21a. Un atacante remoto no autenticado puede explotar este problema para revelar el contenido de la memoria de la pila o bloquear el CodeMeter Runtime Server • https://cdn.wibu.com/fileadmin/wibu_downloads/security_advisories/Advisory_WIBU-210423-01.pdf https://cert-portal.siemens.com/productcert/pdf/ssa-675303.pdf https://us-cert.cisa.gov/ics/advisories/icsa-21-210-02 https://www.tenable.com/security/research/tra-2021-24 • CWE-125: Out-of-bounds Read •
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 •

A vulnerability has been identified in SIMATIC PCS 7 (All versions), SIMATIC WinCC (All versions < V7.5 SP2). Due to an insecure password verification process, an attacker could bypass the password protection set on protected files, thus being granted access to the protected content, circumventing authentication. Se ha identificado una vulnerabilidad en SIMATIC PCS 7 (todas las versiones), SIMATIC WinCC (todas las versiones anteriores a V7.5 SP2). Debido a un proceso de verificación de contraseña no seguro, un atacante podría omitir la protección con contraseña establecida en los archivos protegidos, obteniendo así acceso al contenido protegido, evitando la autenticación • https://cert-portal.siemens.com/productcert/pdf/ssa-944678.pdf • CWE-287: Improper Authentication CWE-288: Authentication Bypass Using an Alternate Path or Channel •
