Summary
generated automatically from NVD dataOpenSSL 0.9.6 and 0.9.7 miscount the number of characters in certain ASN.1 inputs, leading to a read past the end of a buffer when the long form encoding is used. A remote attacker can trigger this by presenting a crafted SSL client certificate, causing the application to crash and resulting in a denial of service. The flaw is rated 5.0 (MEDIUM) under CVSS v2.0, with network access, low complexity and no authentication required.
NVD description
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.
