• Our team is looking to connect with folks who use email services provided by Plesk, or a premium service. If you'd like to be part of the discovery process and share your experiences, we invite you to complete this short screening survey. If your responses match the persona we are looking for, you'll receive a link to schedule a call at your convenience. We look forward to hearing from you!
  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

Shellshock Bash Vulnerability in chrootsh.

New Pleskian
Hello!
We have Plesk Panel 11.5 in Virtuozzo containers (Centos 6 x86_64) and we often provide to our customers the ssh access with chroot - /usr/local/psa/bin/chrootsh.
All we know about Shellshock Vulnerability and we already installed all fixes to bash, but chrootsh-version is still vulnerable.
Here are the results of BashCheck from http://kb.odin.com/en/123006 under chrooted user:

Vulnerable to CVE-2014-6271 (original shellshock)
Vulnerable to CVE-2014-7169 (taviso bug)
bashcheck: line 15: 19226 Segmentation fault bash -c "true $(printf '<<EOF %.0s' {1..79})" 2> /dev/null
Vulnerable to CVE-2014-7186 (redir_stack bug)
Test for CVE-2014-7187 not reliable without address sanitizer
Variable function parser still active, likely vulnerable to yet unknown parser bugs like CVE-2014-6277 (lcamtuf bug)

Do you plan to release updates for chrootsh?
