Summary
The remote host is missing an update for the Huawei EulerOS 'glibc' package(s) announced via the EulerOS-SA-2019-1371 advisory.
Insight
Insight
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.CVE-2017-16997
