Time-of-check time-of-use (toctou) race condition in Microsoft Graphics Component allows an authorized attacker to elevate privileges locally.

The remote Windows host is missing security update 5066782. It is, therefore, affected by multiple vulnerabilities

  - tif_predict.h and tif_predict.c in libtiff 4.0.6 have assertions that can lead to assertion failures in     debug mode, or buffer overflows in release mode, when dealing with unusual tile size like YCbCr with     subsampling. Reported as MSVR 35105, aka Predictor heap-buffer-overflow. (CVE-2016-9535)

  - In IGEL OS before 11, Secure Boot can be bypassed because the igel-flash-driver module improperly verifies     a cryptographic signature. Ultimately, a crafted root filesystem can be mounted from an unverified     SquashFS image. (CVE-2025-47827)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

  - TCG TPM2.0 Reference implementation's CryptHmacSign helper function is vulnerable to Out-of-Bounds read     due to the lack of validation the signature scheme with the signature key's algorithm. See Errata Revision     1.83 and advisory TCGVRT0009 for TCG standard TPM2.0 (CVE-2025-2884)
