CVE-1999-1111

Summary

CVE-1999-1111 is a vulnerability affecting StackGuard before version 1.21. Instead of exploiting a buffer overflow to alter a return address, this issue allows remote attackers to bypass the Random and Terminator Canary security mechanisms using a non-linear attack, directly modifying a pointer to reach a desired return address. This bypass technique undermines the protection provided by these security features, potentially enabling arbitrary code execution.
