Scientific Linux Security Update : bash on SL6.x i386/x86_64
High Nessus Plugin ID 99214
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionSecurity Fix(es) :
- An arbitrary command injection flaw was found in the way bash processed the hostname value. A malicious DHCP server could use this flaw to execute arbitrary commands on the DHCP client machines running bash under specific circumstances. (CVE-2016-0634)
- An arbitrary command injection flaw was found in the way bash processed the SHELLOPTS and PS4 environment variables. A local, authenticated attacker could use this flaw to exploit poorly written setuid programs to elevate their privileges under certain circumstances.
- A denial of service flaw was found in the way bash handled popd commands. A poorly written shell script could cause bash to crash resulting in a local denial of service limited to a specific bash session.
SolutionUpdate the affected bash, bash-debuginfo and / or bash-doc packages.
