openssl (SSA:2006-272-01)
Posted on: 09/29/2006 01:58 PM

New openssl packages are available for Slackware 9.0, 9.1, 10.0, 10.1, 10.2, and -current to fix security issues.

More details about these issues may be found in the Common Vulnerabilities and Exposures (CVE) database:

Here are the details from the Slackware 10.2 ChangeLog:
Upgraded to shared libraries from openssl-0.9.7l.
See openssl package update below.
(* Security fix *)
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.
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.

Give a try. This is another primary FTP site
for Slackware that can be considerably faster than downloading

Thanks to the friendly folks at the OSU Open Source Lab
