CVE-2014-4609
Integer overflow in the get_len function in libavutil/lzo.c in Libav before 0.8.13, 9.x before 9.14, and 10.x before 10.2 allows remote attackers to execute arbitrary code via a crafted Literal Run.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.74%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
