openssl: NULL pointer dereference in X509_issuer_and_serial_hash()

The OpenSSL public API function X509issuerandserialhash attempts to create a unique hash value based on the issuer and serial number data contained within an X509 certificate. However it fails to correctly handle any errors that may occur while parsing the issuer field which might occur if the...

UBUNTU-CVE-2021-3446

A flaw was found in libtpms in versions before 0.8.2. The commonly used integration of libtpms with OpenSSL contained a vulnerability related to the returned IV initialization vector when certain symmetric ciphers were used. Instead of returning the last IV it returned the initial IV to the calle...

RsaPadPSS in wolfcrypt/src/rsa.c in wolfSSL before 4.6.0 has an out-of-bounds write for certain relationships between key size and digest size...

CVE-2020-36160

An issue was discovered in Veritas System Recovery before 21.2. On start-up, it loads the OpenSSL library from \usr\local\ssl. This library attempts to load the from \usr\local\ssl\openssl.cnf configuration file, which does not exist. By default, on Windows systems, users can create directories...

CVE-2020-36167

An issue was discovered in the server in Veritas Backup Exec through 16.2, 20.6 before hotfix 298543, and 21.1 before hotfix 657517. On start-up, it loads the OpenSSL library from the Installation folder. This library in turn attempts to load the /usr/local/ssl/openssl.cnf configuration file, whi...

Multiple vulnerabilities fixed in IBM Aspera

IBM has fixed several vulnerabilities in the Aspera Suite. The vulnerabilities are in the underlying OpenSSL, cURL libcurl and FasterXML jackson databind software. A malicious party could potentially exploit the vulnerabilities to bypassing security measures, accessing sensitive data and from bei...

The vulnerability of the fill-checking function in the AES-NI implementation of the OpenSSL library allows a perpetrator to gain unauthorized access to confidential data.

The vulnerability of the fill-checking function in the AES-NI implementation of the OpenSSL library is related to the lack of protection for service data. Exploiting this vulnerability can allow an attacker operating remotely to gain unauthorized access to confidential data...

The vulnerability of the Montgomery quadradic multiplication algorithm implementation in OpenSSL libraries is related to an error in integer transfer on the x86_64 platform, which allows an attacker to gain unauthorized access to sensitive information.

The vulnerability of the Montgomery quadradic multiplication algorithm implementation in the OpenSSL library is related to an error in arithmetic operations on the x8664 platform. Exploiting this vulnerability may allow a malicious actor, operating remotely, to gain unauthorized access to sensiti...

Denial Of Service (DoS)

OpenSSL is vulnerable to denial of service. It was found that the OpenSSL library did not properly re-initialize its internal state in the SSLlibraryinit function after previous calls to the CRYPTOcleanupallexdata function, which would cause a memory leak for each subsequent SSL connection. This...

UBUNTU-CVE-2020-7041

An issue was discovered in openfortivpn 1.11.0 when used with OpenSSL 1.0.2 or later. tunnel.c mishandles certificate validation because an X509checkhost negative error code is interpreted as a successful return value...

Information disclosure

An exploitable information leak vulnerability exists in the ustream-ssl library of OpenWrt, versions 18.06.4 and 15.05.1. When connecting to a remote server, the server's SSL certificate is checked but no action is taken when the certificate is invalid. An attacker could exploit this behavior by...

CVE-2019-5101

OpenWrt vulnerability CVE-2019-5101 affects the ustream-ssl library (used by tools like wget) in OpenWrt 18.06.4 and 15.05.1. The issue allows information disclosure via MITM because the server certificate is checked but no action is taken for invalid certificates; after SSL initialization and in...

Amazon Linux 2 : curl (ALAS-2019-1162)

libcurl is vulnerable to a heap buffer out-of-bounds read. The function handling incoming NTLM type-2 messages lib/vauth/ntlm.c:ntlmdecodetype2target does not validate incoming data correctly and is subject to an integer overflow vulnerability. Using that overflow, a malicious or broken NTLM serv...

Apache HTTP Server Denial of Service Vulnerability (CNVD-2019-04946)

Apache HTTP Server is the United States Apache Apache Software Foundation, an open source web server. The server is fast, reliable and can be expanded through a simple API. A denial of service vulnerability exists in the handling of client-side renavigation by modssl in httpd in Apache HTTP Serve...
