EulerOS Virtualization 3.0.6.0 : haproxy (EulerOS-SA-2020-1757)

high Nessus Plugin ID 137976

Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

According to the version of the haproxy package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerability :

 - A flaw was found in HAProxy before 2.0.6. In legacy mode, messages featuring a transfer-encoding header missing the 'chunked' value were not being correctly rejected. The impact was limited but if combined with the 'http-reuse always' setting, it could be used to help construct an HTTP request smuggling attack against a vulnerable component employing a lenient parser that would ignore the content-length header as soon as it saw a transfer-encoding one (even if not entirely valid according to the specification).(CVE-2019-18277)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected haproxy package.
