# Security digest: July 1, 2014

1 editorial brief.

## Take stock

- Most can relax: MRLG CVE-2014-3931: 2014 Looking Glass Bug Added to KEV . Network operators, ISPs and exchange points running an MRLG looking glass older than 5.5.0, especially if the fastping helper is installed setuid root.
- None of it touches your stack? Then there is nothing to do today. That is a result, not a failure to read carefully.

## Editorial briefs

- **Most can relax** [MRLG CVE-2014-3931: 2014 Looking Glass Bug Added to KEV](https://erroneo.us/security/briefs/mrlg-looking-glass-cve-2014-3931-fastping-overflow/index.md): MRLG is a niche looking-glass script, the vulnerable fastping helper was only used with Zebra/Quagga routers, and a fix has existed since 2014; only network operators still running an old MRLG need to act.

## Known exploited (CISA KEV)

None.

## Critical advisories

None.
