CVE-2026-107161 2 Cyrusimap, Redhat 8 Cyrus-sasl, Enterprise Linux, Hardened Images and 5 more 2026-11-06 7.5 High
A heap-based buffer overflow flaw was found in Cyrus SASL. The add_to_challenge() function in the DIGEST-MD5 plugin computes the size of the buffer needed for a challenge/response field before DIGEST-MD5 quoting is applied, but does not recompute that size when quoting (escaping special characters) makes the value longer. The under-sized buffer is then passed to strcat(), causing a heap-based out-of-bounds write whose size depends on attacker-controlled input. A malicious or on-path DIGEST-MD5 (or HTTP Digest) server can trigger this flaw in a connecting client by supplying a crafted challenge field, such as realm or nonce, most likely resulting in a crash of the client application.
CVE-2019-19906 8 Apache, Apple, Canonical and 5 more 20 Bookkeeper, Ipados, Iphone Os and 17 more 2026-10-14 7.5 High
cyrus-sasl (aka Cyrus SASL) 2.1.27 has an out-of-bounds write leading to unauthenticated remote denial-of-service in OpenLDAP via a malformed LDAP packet. The OpenLDAP crash is ultimately caused by an off-by-one error in _sasl_add_string in common.c in cyrus-sasl.
CVE-2002-1347 3 Apple, Cyrusimap, Redhat 4 Mac Os X, Mac Os X Server, Cyrus Sasl and 1 more 2026-04-16 9.8 Critical
Multiple buffer overflows in Cyrus SASL library 2.1.9 and earlier allow remote attackers to cause a denial of service and possibly execute arbitrary code via (1) long inputs during user name canonicalization, (2) characters that need to be escaped during LDAP authentication using saslauthd, or (3) an off-by-one error in the log writer, which does not allocate space for the null character that terminates a string.
CVE-2017-12843 2 Cyrusimap, Fedoraproject 2 Cyrus Imap, Fedora 2025-04-20 N/A
Cyrus IMAP before 3.0.3 allows remote authenticated users to write to arbitrary files via a crafted (1) SYNCAPPLY, (2) SYNCGET or (3) SYNCRESTORE command.
