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 Fedora host is missing a security update.
DescriptionThis update addressed two security issues.
CVE-2013-6393: The yaml_parser_scan_tag_uri function in scanner.c in LibYAML before 0.1.5 performs an incorrect cast, which allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via crafted tags in a YAML document, which triggers a heap-based buffer overflow.
CVE-2014-2525: The library is affected by a heap-based buffer overflow which can lead to arbitrary code execution. The vulnerability is caused by lack of proper expansion for the string passed to the yaml_parser_scan_uri_escapes() function. A specially crafted YAML file, with a long sequence of percent-encoded characters in a URL, can be used to trigger the overflow.
Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected perl-YAML-LibYAML package.
