The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-200603-07
(flex: Potential insecure code generation)
Chris Moore discovered a buffer overflow in a special class of
lexicographical scanners generated by flex. Only scanners generated by
grammars which use either REJECT, or rules with a 'variable trailing
context' might be at risk.
An attacker could feed malicious input to an application making
use of an affected scanner and trigger the buffer overflow, potentially
resulting in the execution of arbitrary code.
Avoid using vulnerable grammar in your flex scanners.

All flex users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=sys-devel/flex-2.5.33-r1'
Risk factor :
High / CVSS Base Score : 7.5
CVSS Temporal Score : 5.5
