RedHat: RHSA-2022-7793:01 Moderate: rsync security and enhancement update
Summary
The rsync utility enables the users to copy and synchronize files locally
or across a network. Synchronization with rsync is fast because rsync only
sends the differences in files over the network instead of sending whole
files. The rsync utility is also used as a mirroring tool.
Security Fix(es):
* zlib: heap-based buffer over-read and overflow in inflate() in inflate.c
via a large gzip header extra field (CVE-2022-37434)
