cyrus-sasl: sasl_encode64() does not reliably null-terminate its output

Multiple buffer overflows in the CMU Cyrus SASL library before 2.1.23 might allow remote attackers to execute arbitrary code or cause a denial of service (application crash) via strings that are used as input to the sasl_encode64 function in lib/saslutil.c.

Cyrus 2.0.15, 2.0.16, and 1.6.24 on BSDi 4.2, with IMAP enabled, allows remote attackers to cause a denial of service (hang) using PHP IMAP clients.

Integer overflow in imapparse.c for Cyrus IMAP server 1.4 and 2.1.10 allows remote attackers to execute arbitrary code via a large length value that facilitates a buffer overflow attack, a different vulnerability than CVE-2002-1347.

Stack-based buffer overflow in Cyrus IMAP Server 2.2.4 through 2.2.8, with the imapmagicplus option enabled, allows remote attackers to execute arbitrary code via a long (1) PROXY or (2) LOGIN command, a different vulnerability than CVE-2004-1015.

The argument parser of the PARTIAL command in Cyrus IMAP Server 2.2.6 and earlier allows remote authenticated users to execute arbitrary code via a certain command ("body[p") that is treated as a different command ("body.peek") and causes an index increment error that leads to an out-of-bounds memory corruption.

security flaw

cyrus-sasl before 1.5.24 in Red Hat Linux 7.0 does not properly verify the authorization for a local user, which could allow the users to bypass specified access restrictions.

Buffer overflow in proxyd for Cyrus IMAP Server 2.2.9 and earlier, with the imapmagicplus option enabled, may allow remote attackers to execute arbitrary code, a different vulnerability than CVE-2004-1011.

Off-by-one error in the mysasl_canon_user function in Cyrus IMAP Server 2.2.9 and earlier leads to a buffer overflow, which may allow remote attackers to execute arbitrary code via the username.

Format string vulnerability in the snmp_input function in snmptrapd in CMU SNMP utilities (cmu-snmp) allows remote attackers to execute arbitrary code by sending crafted SNMP messages to UDP port 162.

The argument parser of the FETCH command in Cyrus IMAP Server 2.2.x through 2.2.8 allows remote authenticated users to execute arbitrary code via certain commands such as (1) "body[p", (2) "binary[p", or (3) "binary[p") that cause an index increment error that leads to an out-of-bounds memory corruption.
