Detail
| A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 11.04 - Ubuntu 10.10 - Ubuntu 10.04 LTS - Ubuntu 8.04 LTS - Ubuntu 6.06 LTS Summary: An attacker could send crafted input to Postfix and cause it to crash or run programs. Software Description: - postfix: High-performance mail transport agent Details: Thomas Jarosch discovered that Postfix incorrectly handled authentication mechanisms other than PLAIN and LOGIN when the Cyrus SASL library is used. A remote attacker could use this to cause Postfix to crash, leading to a denial of service, or possibly execute arbitrary code as the postfix user. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 11.04: Ubuntu 10.10: Ubuntu 10.04 LTS: Ubuntu 8.04 LTS: Ubuntu 6.06 LTS: In general, a standard system update will make all the necessary changes.

| Title: | DSA-2233-1 postfix -- several | ||
| Description: | Several vulnerabilities were discovered in Postfix, a mail transfer agent. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2009-2939 The postinst script grants the postfix user write access to /var/spool/postfix/pid, which might allow local users to conduct symlink attacks that overwrite arbitrary files. CVE-2011-0411 The STARTTLS implementation does not properly restrict I/O buffering, which allows man-in-the-middle attackers to insert commands into encrypted SMTP sessions by sending a cleartext command that is processed after TLS is in place. CVE-2011-1720 A heap-based read-only buffer overflow allows malicious clients to crash the smtpd server process using a crafted SASL authentication request. | ||

| 72259 | Postfix SMTP Cyrus SASL Authentication Context Data Reuse Memory Corruption A memory corruption flaw exists in Postfix. The Cyrus SASL library fails to sanitize user-supplied input when authentication types other than PLAIN and LOGIN are used resulting in memory corruption. With a specially crafted request, a remote attacker can potentially execute arbitrary code. |
