CVE-2015-8078
Integer overflow in the index_urlfetch function in imap/index.c in Cyrus IMAP 2.3.19, 2.4.18, and 2.5.6 allows remote attackers to have unspecified impact via vectors related to urlfetch range checks and the section_offset variable.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.75%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
