CVE-2009-3586
Off-by-one error in src/http.c in CoreHTTP 0.5.3.1 and earlier allows remote attackers to cause a denial of service or possibly execute arbitrary code via an HTTP request with a long first line that triggers a buffer overflow.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (6.39%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
