CVE-2018-14352
An issue was discovered in Mutt before 1.10.1 and NeoMutt before 2018-07-16. imap_quote_string in imap/util.c does not leave room for quote characters, leading to a stack-based buffer overflow.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.02%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
