OpenSSL does not properly handle unknown message types
Overview OpenSSL does not properly handle unknown message types, allowing an unauthenticated, remote attacker to cause a denial of service. This vulnerability was addressed in OpenSSL 0.9.6d and 0.9.7. Description OpenSSL implements the Secure Sockets Layer SSL and Transport Layer Security TLS...
OpenSSL does not adequately validate length of Kerberos ticket during SSL/TLS handshake
Overview OpenSSL contains a vulnerability in code that processes SSL/TLS handshakes when configured to use the Kerberos cipher suites. This vulnerability could allow a remote attacker to cause OpenSSL to crash. Description OpenSSL implements the Secure Sockets Layer SSL and Transport Layer Securi...
OpenSSL contains null-pointer assignment in do_change_cipher_spec() function
Overview OpenSSL contains a null-pointer assignment in the dochangecipherspec function which could allow a remote, unauthenticated attacker to cause OpenSSL to crash. Description OpenSSL implements the Secure Sockets Layer SSL and Transport Layer Security TLS protocols and includes a general...
OpenSSL < 0.9.6m / 0.9.7d Multiple Remote DoS
According to its banner, the remote host is using a version of OpenSSL which is older than 0.9.6m / 0.9.7d. There are several bugs in such versions that may allow an attacker to cause a denial of service against the remote host. C Tenable Network Security, Inc. include"compat.inc"; ifdescription...
OpenSSL ChangeCipherSpec denial-of-service vulnerability
A remote attacker could cause an application using OpenSSL to crash by performing a specially crafted SSL/TLS handshake...
Vulnerability in OpenSSL CVE-2004-0079
The Codenomicon TLS Test Tool uncovered a null-pointer assignment in the dochangecipherspec function. A remote attacker could perform a carefully crafted SSL/TLS handshake against a server that used the OpenSSL library in such a way as to cause a crash...
CVE-2003-0851
OpenSSL 0.9.6k allows remote attackers to cause a denial of service crash via large recursion via malformed ASN.1 sequences...
CVE-2003-0543
Integer overflow in OpenSSL 0.9.6 and 0.9.7 allows remote attackers to cause a denial of service crash via an SSL client certificate with certain ASN.1 tag values...
CVE-2003-0544
OpenSSL 0.9.6 and 0.9.7 does not properly track the number of characters in certain ASN.1 inputs, which allows remote attackers to cause a denial of service crash via an SSL client certificate that causes OpenSSL to read past the end of a buffer when the long form is used...
CVE-2003-0543
Integer overflow in OpenSSL 0.9.6 and 0.9.7 allows remote attackers to cause a denial of service crash via an SSL client certificate with certain ASN.1 tag values...
CVE-2003-0545
Double free vulnerability in OpenSSL 0.9.7 allows remote attackers to cause a denial of service crash and possibly execute arbitrary code via an SSL client certificate with a certain invalid ASN.1 encoding...
CVE-2003-0545
Double free vulnerability in OpenSSL 0.9.7 allows remote attackers to cause a denial of service crash and possibly execute arbitrary code via an SSL client certificate with a certain invalid ASN.1 encoding...
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 Advisory] Denial of Service in ASN.1 parsing
-----BEGIN PGP SIGNED MESSAGE----- OpenSSL Security Advisory 4 November 2003 Denial of Service in ASN.1 parsing ================================== Previously, OpenSSL 0.9.6k was released on the 30 September 2003 to address various ASN.1 issues. The issues were found using a test suite from NISCC...
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...
