CyberRota Analysis

AI-Generated

FreeRDP versions prior to 3.29.0 are vulnerable to a null pointer dereference in the smartcard cache request decoders, specifically during SCARD_IOCTL_READCACHEA and SCARD_IOCTL_WRITECACHEA operations. This flaw allows attackers to exploit the vulnerability by sending specially crafted requests, leading to client process termination when smartcard emulation is enabled. Organizations utilizing FreeRDP for remote desktop solutions should prioritize patching to mitigate the risk of service disruption.

Original NVD Description

FreeRDP before 3.29.0 contains a null pointer dereference vulnerability in smartcard cache request decoders that accept NULL NDR pointers for LookupName in SCARD_IOCTL_READCACHEA and SCARD_IOCTL_WRITECACHEA operations. When smartcard emulation is enabled, attackers can send crafted smartcard cache requests with NULL lookup-name pointers to trigger strlen() on a null pointer, causing client process termination.
