-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 [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`).
