CVE-1999-1111

Summary

CVE-1999-1111 is a vulnerability affecting StackGuard before version 1.21. Unlike traditional buffer overflow attacks, this issue allows remote hackers to bypass the security mechanisms of Random and Terminator Canaries. Instead of overflowing a buffer to reach the return address, attackers can directly modify a pointer to manipulate the return address, making it a non-linear attack. This vulnerability poses a significant risk to systems using affected versions of StackGuard and requires urgent patching to mitigate the threat.
