Here are the details from the Slackware 10.2 ChangeLog:
+--------------------------+
patches/packages/openssl-0.9.7l-i486-1_slack10.2.tgz:
 Upgraded to shared libraries from openssl-0.9.7l.
 See openssl package update below.
 (* Security fix *)
patches/packages/openssl-0.9.7l-i486-1_slack10.2.tgz:
 Upgraded to openssl-0.9.7l.
 This fixes a few security related issues:
 During the parsing of certain invalid ASN.1 structures an error
 condition is mishandled. This can result in an infinite loop which
 consumes system memory (CVE-2006-2937). (This issue did not affect
 OpenSSL versions prior to 0.9.7)
 Thanks to Dr S. N. Henson of Open Network Security and NISCC.
 Certain types of public key can take disproportionate amounts of
 time to process. This could be used by an attacker in a denial of
 service attack (CVE-2006-2940).
 Thanks to Dr S. N. Henson of Open Network Security and NISCC.
 A buffer overflow was discovered in the SSL_get_shared_ciphers()
 utility function. An attacker could send a list of ciphers to an
 application that uses this function and overrun a buffer.
 (CVE-2006-3738)
 Thanks to Tavis Ormandy and Will Drewry of the Google Security Team.
 A flaw in the SSLv2 client code was discovered. When a client
 application used OpenSSL to create an SSLv2 connection to a malicious
 server, that server could cause the client to crash (CVE-2006-4343).
 Thanks to Tavis Ormandy and Will Drewry of the Google Security Team.
