Título:	Slackware: Security Advisory (SSA:2017-251-01)
Resumen:	The remote host is missing an update for the 'bash' package(s) announced via the SSA:2017-251-01 advisory.
Descripción:	Summary: The remote host is missing an update for the 'bash' package(s) announced via the SSA:2017-251-01 advisory. Vulnerability Insight: New bash packages are available for Slackware 13.1, 13.37, 14.0, 14.1, and 14.2 to fix security issues. Here are the details from the Slackware 14.2 ChangeLog: +--------------------------+ patches/packages/bash-4.3.048-i586-1_slack14.2.txz: Upgraded. 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. For more information, see: [links moved to references] (* Security fix *) +--------------------------+ Affected Software/OS: 'bash' package(s) on Slackware 13.1, Slackware 13.37, Slackware 14.0, Slackware 14.1, Slackware 14.2. Solution: Please install the updated package(s). CVSS Score: 7.2 CVSS Vector: AV:L/AC:L/Au:N/C:C/I:C/A:C
