CVE-2017-14952
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.10%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
