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.
VPR Score: 5.8
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionTavis Ormandy and Will Drewry discovered multiple flaws in the regular expression handling of PCRE. By tricking a user or service into running specially crafted expressions via applications linked against libpcre3, a remote attacker could crash the application, monopolize CPU resources, or possibly execute arbitrary code with the application's privileges.
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
