slackware
Calendar Grey October 15, 2014
Dist Slackware Esm H88
Updated openssl distributions for Slackware address various security concerns, notably memory leak incidents and denial of service vulnerabilities.
New openssl packages are available for Slackware 13.0, 13.1, 13.37, 14.0, 14.1, and -current to fix security issues

Summary

Here are the details from the Slackware 14.1 ChangeLog: patches/packages/openssl-solibs-1.0.1j-i486-1_slack14.1.txz: Upgraded. (* Security fix *) patches/packages/openssl-1.0.1j-i486-1_slack14.1.txz: Upgraded. This update fixes several security issues: SRTP Memory Leak (CVE-2014-3513): A flaw in the DTLS SRTP extension parsing code allows an attacker, who sends a carefully crafted handshake message, to cause OpenSSL to fail to free up to 64k of memory causing a memory leak. This could be exploited in a Denial Of Service attack. Session Ticket Memory Leak (CVE-2014-3567): When an OpenSSL SSL/TLS/DTLS server receives a session ticket the integrity of that ticket is first verified. In the event of a session ticket integrity check failing, OpenSSL will fail to free memory causing a memory leak. By sending a large number of invalid session tickets an attacker could exploit this issue in a Denial Of Service attack. SSL 3.0 Fallback
