Patch availableMicrosoft Windows Common Log File System (CLFS) driver contains a heap-based buffer overflow vulnerability that allows a local attacker to escalate privileges.
Microsoft Windows Common Log File System (CLFS) driver contains a heap-based buffer overflow vulnerability that allows a local attacker to escalate privileges.
A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().
An attacker operating through local access may attempt exploitation with low privileges. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.
