When netty's multipart decoders are used local information disclosure can occur via the local system temporary directory if temporary storing uploads on the disk is enabled. This only impacts applications running on Java version 6 and lower. Additionally, this vulnerability impacts code running on Unix-like systems, and very old versions of Mac OSX and Windows as they all share the system temporary directory between all users. Reproducible: Always
Fixed in 4.1.77.Final
netty-codec-http-4.1.58 seems to be the highest affected version: https://mvnrepository.com/artifact/io.netty/netty-codec-http/4.1.58.Final But dev-java/netty-4.1.35 does not have the netty-codec-http module. NETTY_MODULES=( "common" "resolver" "buffer" "transport" )
Adjusting summary and whiteboard as we don't have a fixed version in tree yet. (In reply to Volkmar W. Pogatzki from comment #2) > netty-codec-http-4.1.58 seems to be the highest affected version: > https://mvnrepository.com/artifact/io.netty/netty-codec-http/4.1.58.Final > > But dev-java/netty-4.1.35 does not have the netty-codec-http module. > > NETTY_MODULES=( > "common" > "resolver" > "buffer" > "transport" > ) Just to be clear, are you saying we're unaffected here?

Thanks! Invalid then. 9ts64j2: Note that you didn't do anything wrong here, netty is weird and hard to track what vulnerabilities affect us.
