EulerOS Virtualization 2.5.2 : glibc (EulerOS-SA-2019-1086)

critical Nessus Plugin ID 122708

Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

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

- stdlib/canonicalize.c in the GNU C Library (aka glibc or libc6) 2.27 and earlier, when processing very long pathname arguments to the realpath function, could encounter an integer overflow on 32-bit architectures, leading to a stack-based buffer overflow and, potentially, arbitrary code execution.(CVE-2018-11236)

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 glibc package.
