openSUSE_Evergreen_Maintenance_4656 critical openSUSE 13.1 Update This update for dropbear fixes four security issues (bnc#990363): - A format string injection vulnerability allowed remotes attacker to run arbitrary code as root if specific usernames including "%" symbols could be created on the target system. If a dbclient user can control usernames or host arguments, or untrusted input is processed, potentially arbitrary code could have been executed as the dbclient user. - When importing malicious OpenSSH key files via dropbearconvert, arbitrary code could have been executed as the local dropbearconvert user - If particular -m or -c arguments were provided, as used in scripts, dbclient could have executed arbitrary code - dbclient or dropbear server could have exposed process memory to the running user if compiled with DEBUG_TRACE and running with -v Dropbear was updated to the upstream 2016.74 release, including fixes for the following upstream issues: - Port forwarding failure when connecting to domains that have both IPv4 and IPv6 addresses - 100% CPU use while waiting for rekey to complete - Fix crash when fallback initshells() is used scp failing when the local user doesn't exist The following upstream improvements are included: - Support syslog in dbclient, option -o usesyslog=yes - Kill a proxycommand when dbclient exits - Option to exit when a TCP forward fails - Allow specifying commands eg "dropbearmulti dbclient ..." instead of symlinks dropbear-2016.74-2.10.1.i586.rpm dropbear-2016.74-2.10.1.src.rpm dropbear-debuginfo-2016.74-2.10.1.i586.rpm dropbear-debugsource-2016.74-2.10.1.i586.rpm dropbear-2016.74-2.10.1.x86_64.rpm dropbear-debuginfo-2016.74-2.10.1.x86_64.rpm dropbear-debugsource-2016.74-2.10.1.x86_64.rpm
