Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: A critical logical flaw in the SASL state machine swapped a boolean success indicator with an error object, potentially allowing unauthenticated or malformed authentication flows to proceed incorrectly.
Auth Bypass: Using real user ID (Getuid) instead of effective user ID (Geteuid) caused authentication failures or incorrect privilege association when the library ran under modified security contexts (such as setuid binaries).
