Description
Cyrus IMAP before 3.4.2 allows remote attackers to cause a denial of service (multiple-minute daemon hang) via input that is mishandled during hash-table interaction. Because there are many insertions into a single bucket, strcmp becomes slow. This is fixed in 3.4.2, 3.2.8, and 3.0.16.
A flaw was found in cyrus-imapd. A bad string hashing algorithm used in internal hash tables allows user inputs to be stored in predictable buckets. A user may cause a CPU denial of service by maliciously directing many inputs to a single bucket. The highest threat from this vulnerability is to system availability.
