[slackware-security] rsync (SSA:2026-141-02)

New rsync packages are available for Slackware 15.0 and -current to
fix security issues.


Here are the details from the Slackware 15.0 ChangeLog:
+--------------------------+
patches/packages/rsync-3.4.3-i586-1_slack15.0.txz: Upgraded.
This update fixes security issues:
TOCTOU symlink race condition allowing local privilege escalation in daemon
mode without chroot.
Hostname/ACL bypass on an rsync daemon configured with `daemon chroot = /X`
in rsyncd.conf when the chroot tree lacks DNS resolution support.
Integer overflow in the compressed-token decoder enabling remote memory
disclosure to an authenticated daemon peer.
Symlink races on path-based system calls in "use chroot = no" daemon mode.
Out-of-bounds read in the receiver's recv_files() enabling remote
denial-of-service of any client pulling from a malicious server.
Off-by-one out-of-bounds stack write in the rsync client's HTTP CONNECT proxy
handler (`establish_proxy_connection()` in `socket.c`).
