Name of the Vulnerable Software and Affected Versions
GNU C Library (aka glibc) versions 2.14 and other versions
Description
The issue arises from a miscalculation of buffer length in the
vfprintf function, allowing attackers to bypass format-string protection and cause a denial of service, resulting in a segmentation fault and crash. This occurs when a format string contains a large number of format specifiers, triggering desynchronization within the buffer size handling.Recommendations
For GNU C Library (aka glibc) versions 2.14 and other versions, consider disabling the
vfprintf function as a temporary workaround until a patch is available. Restrict the use of format strings with multiple format specifiers to minimize the risk of exploitation.Explorabilidade
