CVE-2021-32055
Mutt 1.11.0 through 2.0.x before 2.0.7 (and NeoMutt 2019-10-25 through 2021-05-04) has a $imap_qresync issue in which imap/util.c has an out-of-bounds read in situations where an IMAP sequence set ends with a comma.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.55%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
