Vulnerability in OpenSSL CVE-2003-0851

A flaw in OpenSSL 0.9.6k only would cause certain ASN.1 sequences to trigger a large recursion. On platforms such as Windows this large recursion cannot be handled correctly and so the bug causes OpenSSL to crash. A remote attacker could exploit this flaw if they can send arbitrary ASN.1 sequence...

OpenSSL 0.9.6k does not properly handle ASN.1 sequences

Overview A vulnerability in the way OpenSSL handles ASN.1 elements could allow a remote attacker to cause a denial of service on systems running Microsoft Windows. Description OpenSSL implements the Secure Sockets Layer SSL and Transport Layer Security TLS protocols and includes a general purpose...

CVE-2002-1568

OpenSSL 0.9.6e uses assertions when detecting buffer overflow attacks instead of less severe mechanisms, which allows remote attackers to cause a denial of service crash via certain messages that cause OpenSSL to abort from a failed assertion, as demonstrated using SSLv2 CLIENTMASTERKEY messages,...

OpenSSL ASN.1 parser insecure memory deallocation

Overview A vulnerability in the way OpenSSL deallocates memory used to store ASN.1 structures could allow a remote attacker to execute arbitrary code with the privileges of the process using the OpenSSL library. Description OpenSSL implements the Secure Sockets Layer SSL and Transport Layer...

OpenSSL does not securely handle invalid public key when configured to ignore errors

Overview A vulnerability in the way OpenSSL handles invalid public keys in client certificate messages could allow a remote attacker to cause a denial of service. This vulnerability requires as a precondition that an application is configured to ignore public key decoding errors, which is typical...

Vulnerability in OpenSSL CVE-2003-0544

Incorrect tracking of the number of characters in certain ASN.1 inputs could allow remote attackers to cause a denial of service crash by sending an SSL client certificate that causes OpenSSL to read past the end of a buffer when the long form is used. Found by NISCC...
