Summary

The NtUserConsoleControl function in win32k.sys in Microsoft Windows XP SP2 and SP3, and Server 2003 before SP1, allows local administrators to bypass unspecified "security software" and gain privileges via a crafted call that triggers an overwrite of an arbitrary memory location. NOTE: the vendor disputes the significance of this report, stating that 'the Administrator to SYSTEM "escalation" is not a security boundary we defend.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
