Name of the Vulnerable Software and Affected Versions: glibc versions prior to 2.15

Description: The issue allows local users to cause a denial of service, resulting in a segmentation fault, by providing a large string of 0s to scanf and related functions in glibc.

Recommendations: For versions prior to 2.15, consider restricting the input to scanf and related functions to prevent the denial of service. As a temporary workaround, limit the length of input strings to prevent the segmentation fault until a patch is available.
