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: 6.7
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionSecurity Fix(es) :
- It was discovered that PHP did not properly protect against the HTTP_PROXY variable name clash. A remote attacker could possibly use this flaw to redirect HTTP requests performed by a PHP script to an attacker- controlled proxy via a malicious HTTP request.
Bug Fix(es) :
- Previously, an incorrect logic in the SAPI header callback routine caused that the callback counter was not incremented. Consequently, when a script included a header callback, it could terminate unexpectedly with a segmentation fault. With this update, the callback counter is properly managed, and scripts with a header callback implementation work as expected.
SolutionUpdate the affected packages.
