Description:
Some vulnerabilities have been reported in OpenSSL, which can be exploited by malicious people to cause a DoS (Denial of Service) and compromise a vulnerable system.
1) An error in the processing of certain invalid ASN.1 structures can be exploited to cause an infinite loop and consume system memory in an application using OpenSSL to process ASN.1 data from untrusted sources.
NOTE: This does not affect versions prior to 0.9.7.
2) Certain types of public keys take overly long time to process and can be exploited to cause a DoS in an application using OpenSSL to process ASN.1 data from untrusted sources.
3) An error in the "SSL_get_shared_ciphers()" function can be exploited to cause a buffer overflow by sending a list of ciphers to an application using the vulnerable function.
Successful exploitation allows execution of arbitrary code.
4) An error in the SSLv2 client code can be exploited by a malicious server to crash a vulnerable client using OpenSSL to create an SSLv2 connection to the server.
