[slackware-security] samba (SSA:2016-189-01)
New samba packages are available for Slackware 14.0, 14.1, 14.2, and -current to fix security issues.
Here are the details from the Slackware 14.2 ChangeLog: +--------------------------+ patches/packages/samba-4.4.5-i586-1_slack14.2.txz: Upgraded. This release fixes a security issue: Client side SMB2/3 required signing can be downgraded. It's possible for an attacker to downgrade the required signing for an SMB2/3 client connection, by injecting the SMB2_SESSION_FLAG_IS_GUEST or SMB2_SESSION_FLAG_IS_NULL flags. This means that the attacker can impersonate a server being connected to by Samba, and return malicious results. For more information, see: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-2119 (* Security fix *) +--------------------------+
Where to find the new packages: +-----------------------------+
Thanks to the friendly folks at the OSU Open Source Lab (http://osuosl.org) for donating FTP and rsync hosting to the Slackware project! :-)
