Description Thomas Leroy 2022-06-13 08:38:36 UTC
CVE-2022-30780

Lighttpd 1.4.56 through 1.4.58 allows a remote attacker to cause a denial of
service (CPU consumption from stuck connections) because
connection_read_header_more in connections.c has a typo that disrupts use of
multiple read operations on large headers.

Upstream fix:
https://github.com/lighttpd/lighttpd1.4/commit/b03b86f47b0d5a553137f081fadc482b4af1372d

Comment 1 Thomas Leroy 2022-06-13 08:40:31 UTC
The bug was introduced in v1.4.56 by this commit [0], therefore SUSE:SLE-12:Update/lighttpd v1.4.35 is not affected.
openSUSE codestreams are already fixed. Closing.
