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 VMware ESXi host is missing a security-related patch.
DescriptionThe remote ESXi host is affected by multiple denial of service vulnerabilities in the glibc library :
- A buffer overflow condition exists in the extend_buffers() function in file posix/regexec.c due to improper validation of user-supplied input when handling multibyte characters in a regular expression. An unauthenticated, remote attacker can exploit this, via a crafted regular expression, to corrupt the memory, resulting in a denial of service. (CVE-2013-0242)
- A stack-based buffer overflow condition exists in the getaddrinfo() function in file posix/getaddrinfo.c due to improper validation of user-supplied input during the handling of domain conversion results. An unauthenticated, remote attacker can exploit this to cause a denial of service by using a crafted host name or IP address that triggers a large number of domain conversion results. (CVE-2013-1914)
SolutionApply the appropriate patch according to the vendor advisory that pertains to ESXi version 5.0 / 5.1 / 5.5.
