Stack-based buffer overflow in netgroup cache

CVE-2024-33599

What is CVE-2024-33599?

The Name Service Cache Daemon (nscd) has a vulnerability that may lead to a stack-based buffer overflow when its fixed-size cache is filled by incoming client requests. This exploit occurs when a subsequent client tries to access netgroup data, causing the overflow due to the inadequate handling of cached items. This issue originated in glibc version 2.15 when the caching feature was implemented in nscd. It is important for users to review and update their systems to mitigate potential risks associated with this flaw.
