Debian Security Advisory DSA 1087-1 (postgresql)

The remote host is missing an update to postgresql announced via advisory DSA 1087-1. Several encoding problems have been discovered in PostgreSQL, a popular SQL database. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2006-2313 Akio Ishida and Yasuo Ohgaki discovered a weakness in the handling of invalidly-encoded multibyte text data which could allow an attacker to inject arbitrary SQL commands. CVE-2006-2314 A similar problem exists in client-side encodings (such as SJIS, BIG5, GBK, GB18030, and UHC) which contain valid multibyte characters that end with the backslash character. An attacker could supply a specially crafted byte sequence that is able to inject arbitrary SQL commands. This issue does not affect you if you only use single-byte (like SQL_ASCII or the ISO-8859-X family) or unaffected multibyte (like UTF-8) encodings. psycopg and python-pgsql use the old encoding for binary data and may have to be updated. The old stable distribution (woody) is affected by these problems but we're unable to correct the package.

For the stable distribution (sarge) these problems have been fixed in version 7.4.7-6sarge2. For the unstable distribution (sid) these problems have been fixed in version 7.4.13-1. We recommend that you upgrade your postgresql packages. https://secure1.securityspace.com/smysecure/catid.html?in=DSA%201087-1
