Summary
CVE-1999-1111 is a vulnerability impacting StackGuard versions prior to 1.21. Instead of exploiting a buffer overflow to change a return address, attackers can bypass the security mechanisms of Random and Terminator Canaries through a non-linear attack, enabling them to directly modify a pointer to a return address. This allows remote attackers to gain unauthorized control over program execution flow.
