patches/packages/bash-4.1.017-x86_64-2_slack13.1.txz
This update fixes two security issues found in bash before 4.4:
The expansion of '\h' in the prompt string allows remote authenticated users
to execute arbitrary code via shell metacharacters placed in 'hostname' of a
machine. The theoretical attack vector is a hostile DHCP server providing a
crafted hostname, but this is unlikely to occur in a normal Slackware
configuration as we ignore the hostname provided by DHCP.
Specially crafted SHELLOPTS+PS4 environment variables used against bogus
setuid binaries using system()/popen() allowed local attackers to execute
arbitrary code as root.
