Description Wolfgang Frisch 2020-01-30 08:54:11 UTC

CVE-2019-20444

HttpObjectDecoder.java in Netty before 4.1.44 allows an HTTP header that lacks a
colon, which might be interpreted as a separate header with an incorrect syntax,
or might be interpreted as an "invalid fold."

Comment 1 Silvio Moioli 2020-03-09 10:00:43 UTC

Side note: from a strict SUSE Manager product perspective, this vulnerability does not affect the product as we do not make use of any HTTP capability of netty (we use it exclusively for async I/O).

Comment 2 Julio González Gil 2020-03-09 13:27:00 UTC

Can this be assigned to the SUSE Manager team (galaxy-bugs@suse.de, actual maintainers) rather than me directly?

Worst case, assign it to Silvio.

Comment 3 Marcus Meissner 2020-04-15 15:05:40 UTC

as we are not using the functionality, I marked it as "ignore" now.

But if you find the time to fix, feel free.

Comment 4 Thomas Florio 2022-03-11 14:48:30 UTC

I guess this issue can be resolved. All SUSE Manager versions (HEAD, 4.2, 4.1) are using netty 4.1.44, which, if I understood correctly, is not affected by this vulnerability.

Comment 5 Wolfgang Frisch 2022-03-31 08:06:23 UTC

Closing.
