What is CVE-2012-0039?

GLib versions up to 2.31.8 are susceptible to a vulnerability in the g_str_hash function that allows attackers to create predictable hash collisions. This could lead to potential denial-of-service conditions through excessive CPU consumption caused by crafted input targeting applications that utilize hash tables. Although the function itself is not inherently vulnerable, the lack of limitations on hash collision triggering poses risks for users relying on default implementations.
