Detailed vulnerability description
The vulnerability allows a local user to cause a denial of service.
The vulnerability exists due to an out-of-bounds read in filesystem glob matching in GetMatchingPaths when parsing crafted filesystem path patterns. A local user can invoke glob matching on a crafted path to cause a denial of service.
