Release Information

Statement introduced in Junos OS Release 11.2.

Description

Set the maximum decompression ratio of the size of decompressed data to the size of compressed data.

Some attacks are introduced through compressed content. When the content is decompressed, it can inflate to a very large size taking up valuable system resources resulting in denial of service. This type of attack can be recognized by the ratio of the size of decompressed data to the size of compressed data. Keep in mind, however, that a higher ratio lessens the chance of detecting this type of attack.
