openSUSE Security Update: Security update for exim ______________________________________________________________________________
Announcement ID: openSUSE-SU-2016:0721-1 Rating: important References: #968844 Cross-References: CVE-2016-1531 Affected Products: openSUSE Leap 42.1 openSUSE 13.2 ______________________________________________________________________________
An update that fixes one vulnerability is now available.
Description:
This update to exim 4.86.2 fixes the following issues:
* CVE-2016-1531: local privilege escalation for set-uid root exim when using 'perl_startup' (boo#968844)
Important: Exim now cleans the complete execution environment by default. This affects Exim and subprocesses such as transports calling other programs. The following new options are supported to adjust this behaviour: * keep_environment * add_environment A warning will be printed upon startup if none of these are configured.
Also includes upstream changes, improvements and bug fixes: * Support for using the system standard CA bundle. * New expansion items $config_file, $config_dir, containing the file and directory name of the main configuration file. Also $exim_version. * New "malware=" support for Avast. * New "spam=" variant option for Rspamd. * Assorted options on malware= and spam= scanners. * A commandline option to write a comment into the logfile. * A logging option for slow DNS lookups. * New ${env {<variable>}} expansion. * A non-SMTP authenticator using information from TLS client certificates. * Main option "tls_eccurve" for selecting an Elliptic Curve for TLS. * Main option "dns_trust_aa" for trusting your local nameserver at the same level as DNSSEC.
