CVE-2017-18189
In the startread function in xa.c in Sound eXchange (SoX) through 14.4.2, a corrupt header specifying zero channels triggers an infinite loop with a resultant NULL pointer dereference, which may allow a remote attacker to cause a denial-of-service.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.05%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
