This vulnerability can be triggered by supplying malicious input that decompresses to a very big size (via a network stream or a file) or by sending a huge skippable chunk.

HIGH 7.5EPSS 6.74%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (6.74%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

The Snappy frame decoder function doesn't restrict the chunk length which may lead to excessive memory usage. Beside this it also may buffer reserved skippable chunks until the whole chunk was received which may lead to excessive memory usage as well. This vulnerability can be triggered by supplying malicious input that decompresses to a very big size (via a network stream or a file) or by sending a huge skippable chunk.
