[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...

Multiple vulnerabilities in S/MIME implementations

Overview Multiple vulnerabilities exist in different vendors' S/MIME Secure/Multipurpose Internet Mail Extensions implementations. The impacts of these vulnerabilities are varied and range from denial of service to potential remote execution of arbitrary code. Description The U.K. National...

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-2003-0544

OpenSSL 0.9.6 and 0.9.7 are affected by DoS vulnerabilities stemming from ASN.1 parsing issues, specifically CVE-2003-0544 (incorrect character counting in long-form ASN.1 inputs causing a crash via an SSL client certificate) and CVE-2003-0543 (integer overflow in ASN.1 handling). Affected produc...

CVE-2003-0545

OpenSSL 0.9.7 is vulnerable to a double free via an invalid ASN.1 encoding in an SSL client certificate, allowing remote DoS and potential code execution. Multiple sources (CVE-2003-0545) confirm the issue as a vulnerability in OpenSSL 0.9.7 and note that advisories reference the 0.9.7c release a...
