SSH Communications Secure Shell vulnerable to DoS via malformed BER/DER packet

Overview SSH Communications' Secure Shell contains vulnerabilities in ASN.1 libraries that may allow remote attackers to cause a denial-of-service situation, or potentially execute arbitrary code on the server. Description SSH Communications' Secure Shell contains a vulnerability in the decoding ...

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...

CVE-2003-0545

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-2003-0544

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...

OpenSSL security update

Upgraded OpenSSL packages are available for Slackware 8.1, 9.0, 9.1, and -current. These fix problems with ASN.1 parsing which could lead to a denial of service. It is not known whether the problems could lead to the running of malicious code on the server, but it has not been ruled out. We...

Vulnerability in OpenSSL CVE-2003-0545

Certain ASN.1 encodings that were rejected as invalid by the parser could trigger a bug in the deallocation of the corresponding data structure, corrupting the stack, leading to a crash. Found by NISCC...
