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: 3.6
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionIt was found that getaddrinfo() did not limit the amount of stack memory used during name resolution. An attacker able to make an application resolve an attacker-controlled hostname or IP address could possibly cause the application to exhaust all stack memory and crash. (CVE-2013-1914)
A flaw was found in the regular expression matching routines that process multibyte character input. If an application utilized the glibc regular expression matching mechanism, an attacker could provide specially crafted input that, when processed, would cause the application to crash. (CVE-2013-0242)
This update also fixes the following bugs :
- The improvements made in a previous update to the accuracy of floating point functions in the math library caused performance regressions for those functions. The performance regressions were analyzed and a fix was applied that retains the current accuracy but reduces the performance penalty to acceptable levels.
- It was possible that a memory location freed by the localization code could be accessed immediately after, resulting in a crash. The fix ensures that the application does not crash by avoiding the invalid memory access.
SolutionUpdate the affected packages.
