heads up when running roller from master branch

[Michael Bien <mb...@gmail.com>]

Hello Everyone,

Just a heads up in case you are building and running apache roller from 
master, please rebuild your instance with the latest changes.

It contains an important dependency update 
(https://github.com/apache/roller/pull/106) for log4j 2 which suffered 
from a RCE security vulnerability, which was fixed in the latest version.

Apache Roller 6.0.2 (latest release) should not be affected by this 
particular vulnerability since it still uses the old log4j 1 library.

best regards,

michael

yeah roller itself did log with log4j 1, however it did pull log4j 2 too 
due to the fact that struts was/is using it i just noticed.

So I retract my statement that roller 6.0.2 should not be affected by 
this - the attack surface is just smaller.

i unified everything to slf4j and mapped it to log4j 2 as impl some time 
ago but this is not in 6.0.2:
https://github.com/apache/roller/pull/68

HEAD on master is using slf4j -> log4j 2.15.0 which contains the fix as 
previously mentioned

(i personally use a slf4j -> JFR bridge for my own blog.

regards,
michael

Nice! I did not remember that 6.0.2 still used Log4j 1.
