USN-5051-1: OpenSSL vulnerabilities

John Ouyang discovered that OpenSSL incorrectly handled decrypting SM2 data. A remote attacker could use this issue to cause applications using OpenSSL to crash, resulting in a denial of service, or possibly change application behaviour. CVE-2021-3711 Ingo Schwarze discovered that OpenSSL...

CVE-2021-3712

ASN.1 strings are represented internally within OpenSSL as an ASN1STRING structure which contains a buffer holding the string data and a field holding the buffer length. This contrasts with normal C strings which are repesented as a buffer for the string data which is terminated with a NUL 0 byte...

CVE-2021-3712

It was found that openssl assumed ASN.1 strings to be NUL terminated. A malicious actor may be able to force an application into calling openssl function with a specially crafted, non-NUL terminated string to deliberately hit this bug, which may result in a crash of the application, causing a...

CVE-2021-3712

The CVE-2021-3712 issue affects OpenSSL where ASN1_STRING data may not be NUL-terminated if constructed directly (or via ASN1_STRING_set0), causing read-buffer overreads when many OpenSSL print/name-constraining paths handle such ASN.1 strings. Exploitation could crash the application (DoS) or di...
