CVE-2016-8859
Multiple integer overflows in the TRE library and musl libc allow attackers to cause memory corruption via a large number of (1) states or (2) tags, which triggers an out-of-bounds write.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.36%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
