What is CVE-2003-0851?

An issue in OpenSSL versions prior to 0.9.7 can be exploited by remote attackers to cause a denial of service condition. This occurs through the processing of malformed ASN.1 sequences, which can result in a crash due to excessive recursion during parsing. This vulnerability underscores the importance of proper input validation and the necessity of keeping security libraries up to date to mitigate risks.
