libspring-2.5-java - information disclosure

It was discovered that the Spring Framework contains an information
disclosure vulnerability in the processing of certain Expression
Language (EL) patterns, allowing attackers to access sensitive
information using HTTP requests.

NOTE: This update adds a springJspExpressionSupport context parameter
which must be manually set to false when the Spring Framework runs
under a container which provides EL support itself.

For the stable distribution (squeeze), this problem has been fixed in
version 2.5.6.SEC02-2+squeeze1.

We recommend that you upgrade your libspring-2.5-java packages.
