CVE-2019-15502
The TeamSpeak client before 3.3.2 allows remote servers to trigger a crash via the 0xe2 0x81 0xa8 0xe2 0x81 0xa7 byte sequence, aka Unicode characters U+2068 (FIRST STRONG ISOLATE) and U+2067 (RIGHT-TO-LEFT ISOLATE).
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.73%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
