CVE-1999-1303

Summary

CVE-1999-1303 is a significant vulnerability affecting SCO UNIX 4.2 and earlier versions. This issue lies in the prwarn function, which enables local users to exploit the flaw and ultimately gain root access to the system. By manipulating the format string in a specially crafted input, attackers can trigger a stack buffer overflow, escalating their privileges to the highest level. This vulnerability poses a serious threat, as local users with minimal permissions can potentially gain full control over the affected system. Systems running SCO UNIX 4.2 should be urgently updated to mitigate this risk.
