EulerOS Virtualization 2.5.3 : glibc (EulerOS-SA-2019-1257)

high Nessus Plugin ID 123725

Language:

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 :

 - elf/dl-load.c in the GNU C Library (aka glibc or libc6) 2.19 through 2.26 mishandles RPATH and RUNPATH containing $ORIGIN for a privileged (setuid or AT_SECURE) program, which allows local users to gain privileges via a Trojan horse library in the current working directory, related to the fillin_rpath and decompose_rpath functions. This is associated with misinterpretion of an empty RPATH/RUNPATH token as the './' directory. NOTE: this configuration of RPATH/RUNPATH for a privileged program is apparently very uncommon most likely, no such program is shipped with any common Linux distribution.i1/4^CVE-2017-16997i1/4%0

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.
