patches/packages/less-653-x86_64-1_slack15.0.txz: Upgraded.
This update patches a security issue:
less through 653 allows OS command execution via a newline character in the
name of a file, because quoting is mishandled in filename.c. Exploitation
typically requires use with attacker-controlled file names, such as the files
extracted from an untrusted archive. Exploitation also requires the LESSOPEN
environment variable, but this is set by default in many common cases.
For more information, see:

(* Security fix *)
