Category:	Debian Local Security Checks
Title:	Debian: Security Advisory (DSA-1852-1)
Summary:	The remote host is missing an update for the Debian 'fetchmail' package(s) announced via the DSA-1852-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'fetchmail' package(s) announced via the DSA-1852-1 advisory. Vulnerability Insight: It was discovered that fetchmail, a full-featured remote mail retrieval and forwarding utility, is vulnerable to the 'Null Prefix Attacks Against SSL/TLS Certificates' recently published at the Blackhat conference. This allows an attacker to perform undetected man-in-the-middle attacks via a crafted ITU-T X.509 certificate with an injected null byte in the subjectAltName or Common Name fields. Note, as a fetchmail user you should always use strict certificate validation through either these option combinations: sslcertck ssl sslproto ssl3 (for service on SSL-wrapped ports) or sslcertck sslproto tls1 (for STARTTLS-based services) For the oldstable distribution (etch), this problem has been fixed in version 6.3.6-1etch2. For the stable distribution (lenny), this problem has been fixed in version 6.3.9~ rc2-4+lenny1. For the testing distribution (squeeze), this problem will be fixed soon. For the unstable distribution (sid), this problem has been fixed in version 6.3.9~ rc2-6. We recommend that you upgrade your fetchmail packages. Affected Software/OS: 'fetchmail' package(s) on Debian 4, Debian 5. Solution: Please install the updated package(s). CVSS Score: 6.4 CVSS Vector: AV:N/AC:L/Au:N/C:P/I:P/A:N
