Summary
Denial of Service vulnerability due to stack exhaustion in glibc used by Junos
Impact
Local attackers can cause a partial denial of service on services provided by rpd.
Solution
New builds of Junos OS software are available from Juniper.
Insight
A stack consumption vulnerability in the regcomp implementation in the GNU C Library allows an attacker to cause a denial of service via a regular expression containing adjacent repetition operators or adjacent bounded repetitions. Junos uses regular expressions in several places within the CLI.
Affected
