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 Debian host is missing a security-related update.
DescriptionAlexander Sulfrian discovered a buffer overflow in the yy_get_next_buffer() function generated by Flex, which may result in denial of service and potentially the execution of code if operating on data from untrusted sources.
Affected applications need to be rebuild. bogofilter will be rebuild against the updated flex in a followup update. Further affected applications should be reported at the bug referenced above.
SolutionUpgrade the flex packages.
For the stable distribution (jessie), this problem has been fixed in version 2.5.39-8+deb8u1.
