New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200508-17 (libpcre: Heap integer overflow)
libpcre fails to check certain quantifier values in regular expressions for sane values.
An attacker could possibly exploit this vulnerability to execute arbitrary code by sending specially crafted regular expressions to applications making use of the libpcre library.
There is no known workaround at this time.
SolutionAll libpcre users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-libs/libpcre-6.3'
