What is CVE-2002-1347?

The Cyrus SASL library, specifically versions 2.1.9 and earlier, contains multiple vulnerabilities that could allow remote attackers to exploit buffer overflow issues. These vulnerabilities arise from inappropriate handling of long input during user name canonicalization, improper character escaping during LDAP authentication via saslauthd, and an off-by-one error in the log writer that fails to allocate space for the null terminator. These flaws could lead to a denial of service and may enable execution of arbitrary code by an attacker.
