Last modified

CVE-2002-1347 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. 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.. EPSS estimates a 7.08% chance of exploitation in the next 30 days.
