Software update: pfSense 2.2.4

Spread the love

An update for version 2.2 of pfSense has been released. This package is based on the FreeBSD operating system and focuses on router and firewall tasks. It started in 2004 as a fork of m0n0wall due to differing views among the developers and over the years has grown into a router and firewall package that can be deployed in both small and very large environments. For more information, please refer to this page. The changelog for pfSense 2.2.4 looks like this:

Security Fixes and Errata

  • pfSense-SA-15_07.webgui: Multiple Stored XSS Vulnerabilities in the pfSense WebGUI
    • The complete list of affected pages and fields is listed in the linked SA.
  • FreeBSD-SA-15:13.tcp: Resource exhaustion due to sessions stuck in LAST_ACK state. Note this only applies to scenarios where ports listening on pfSense itself (not things passed through via NAT, routing or bridging) are opened to untrusted networks. This doesn’t apply to the default configuration.
  • Note: FreeBSD-SA-15:13.openssl does not apply to pfSense. pfSense did not include a vulnerable version of OpenSSL, and thus was not vulnerable.
  • Further fixes for file corruption in various cases during an unclean shut down (crash, power loss, etc.). #4523
    • Fixed pw in FreeBSD to address passwd/group corruption
    • Fixed config.xml writing to use fsync properly to avoid cases when it could end up empty. #4803
    • Removed the ‘sync’ option from filesystems for new full installs and full upgrades now that the real fix is ​​in place.
    • Removed softupdates and journaling (AKA SU+J) from NanoBSD, they remain on full installs. #4822
  • The forcesync patch for #2401 is still considered harmful to the filesystem and has been kept out. As such, there may be some noticeable slowness with NanoBSD on certain slower disks, especially CF cards and to a lesser extent, SD cards. If this is a problem, the filesystem may be kept read-write on a permanent basis using the option on Diagnostics > NanoBSD. With the other above changes, risk is minimal. We recommend replacing the affected CF/SD media by a new, faster card as soon as possible. #4822
  • Upgraded PHP to 5.5.27 to address CVE-2015-3152 #4832
  • Lowered SSH LoginGraceTime from 2 minutes to 30 seconds to mitigate the impact of MaxAuthTries bypass bug. note sshlockout will lock out offending IPs in all past, current and future versions. #4875
