WEBppliance Pro for Linux 3.5.1 (LH)Installation and Upgrade Details



WEBppliance Pro 3.5.1 provides a security patch that resolves the Sendmail and OpenSSL security vulnerability.
It also fixes some of the high priority bugs reported in Webppliance Pro 3.5.0.

Compatibility : 

You can upgrade to WEBppliance PRO 3.5.1 from any of the following versions of WEBppliance

  • Version 3.0.x
  • Version 3.1.x
  • Version 3.5.0

Fix provided for the following security issues :

  • Sendmail vulnerability that allows local and possibly remote attackers to gain root privileges. 

    There is a vulnerability in Sendmail versions prior to and including 8.12.8. The address parser performs insufficient bounds checking in certain conditions due to a char to int conversion, making it possible for an attacker to take control of the application. Although no exploit currently exists, this issue is probably locally exploitable and may also be remotely exploitable. 

    Advisory details for the security patch are available at the following URL:

  • OpenSSL vulnerability that allows a potential timing-based attack and a modified Bleichenbacher attack. 

    The SSL and TLS components for OpenSSL 0.9.6i and earlier, 0.9.7, and 0.9.7a allow remote attackers to perform an unauthorized RSA private key operation via a modified Bleichenbacher attack that uses a large number of SSL or TLS connections using PKCS #1 v1.5 padding that cause OpenSSL to leak information regarding the relationship between ciphertext and the associated plaintext, aka the "Klima-Pokorny-Rosa attack." 

    Advisory details for the security patch are available at the following URL:

Other Resolved Issues :

  • If your WEBppliance has a deleted reseller, this would cause upgrade to fail. This has been corrected in 3.5.1.     
  • If your WEBppliance has reseller sites with disabled disk quota, upgrade would fail. This has been corrected in 3.5.1.     
  • Previously, upgrade would stop at the first site that fails upgrade. Upgrade now processes all sites during an upgrade logging info on all sites that fails to upgrade correctly. If any site failed upgrade, WEBppliance doesn't exit Maintenance mode. The user must repair all failed sites, and restart WEBppliance to complete the upgrade.     
  • RedHat 7.3 broke out into the rpm perl-CGI. On an upgrade or a new install of WEBppliance Pro 3.5.0, this RPM isn't installed and perl CGIs are broken because of this. This new RPM is now included in WEBppliance Pro 3.5.1.     
  • Corrects a problem with restoring a backup from some ftp servers.     
  • A missing Appliance Admin email address no longer causes an upgrade to fail. Logging of upgrade has been improved.     
  • Two or more domains with the exact same 1st 30 characters no longer cause upgrade to fail.
