Description

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

  • Double free in i18n/zonemeta.cpp in International Components for Unicode (ICU) for C/C++ through 59.1 allows remote attackers to execute arbitrary code via a crafted string, aka a 'redundant UVector entry clean up function call' issue.(CVE-2017-14952)

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.
