Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information or perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary condition when using the "fgetss()" function to read data with stripping tags. A remote attacker can supply data that will cause this function to read past the allocated buffer, trigger out-of-bounds read error and read contents of memory on the system or crash the application.
