Debian 9890 Published by

The following updates has been released for Debian:

[DLA 986-1] zookeeper security update
[DLA 987-1] request-tracker4 security update
[DSA 3882-1] request-tracker4 security update
[DSA 3883-1] rt-authen-externalauth security update



[DLA 986-1] zookeeper security update

Package : zookeeper
Version : 3.4.5+dfsg-2+deb7u1
CVE ID : CVE-2017-5637
Debian Bug : 863811

It was discovered that Zookeeper, a service for maintaining
configuration information, didn't restrict access to the computationally
expensive wchp/wchc commands which could result in denial of service by
elevated CPU consumption.

This update disables those two commands by default. The new
configuration option "4lw.commands.whitelist" can be used to whitelist
commands selectively (and the full set of commands can be restored
with '*')

For Debian 7 "Wheezy", these problems have been fixed in version
3.4.5+dfsg-2+deb7u1.

We recommend that you upgrade your zookeeper packages.

[DLA 987-1] request-tracker4 security update

Package : request-tracker4
Version : 4.0.7-5+deb7u5
CVE ID : CVE-2016-6127 CVE-2017-5361 CVE-2017-5943 CVE-2017-5944

Multiple vulnerabilities have been discovered in Request Tracker, an
extensible trouble-ticket tracking system. The Common Vulnerabilities
and Exposures project identifies the following problems:

CVE-2016-6127

It was discovered that Request Tracker is vulnerable to a cross-site
scripting (XSS) attack if an attacker uploads a malicious file with
a certain content type. Installations which use the
AlwaysDownloadAttachments config setting are unaffected by this
flaw. The applied fix addresses all existant and future uploaded
attachments.

CVE-2017-5361

It was discovered that Request Tracker is vulnerable to timing
side-channel attacks for user passwords.

CVE-2017-5943

It was discovered that Request Tracker is prone to an information
leak of cross-site request forgery (CSRF) verification tokens if a
user is tricked into visiting a specially crafted URL by an
attacker.

CVE-2017-5944

It was discovered that Request Tracker is prone to a remote code
execution vulnerability in the dashboard subscription interface. A
privileged attacker can take advantage of this flaw through
carefully-crafted saved search names to cause unexpected code to be
executed. The applied fix addresses all existant and future saved
searches.

Additionally to the above mentioned CVEs, this update works around
CVE-2015-7686 in Email::Address which could induce a denial of service
of Request Tracker itself.

For Debian 7 "Wheezy", these problems have been fixed in version
4.0.7-5+deb7u5.

We recommend that you upgrade your request-tracker4 packages.
