CVE-2012-0039

First published: Mon Jan 09 2012(Updated: )

** DISPUTED ** GLib 2.31.8 and earlier, when the g_str_hash function is used, computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table. NOTE: this issue may be disputed by the vendor; the existence of the g_str_hash function is not a vulnerability in the library, because callers of g_hash_table_new and g_hash_table_new_full can specify an arbitrary hash function that is appropriate for the application.

    CVE-2012-0039 affects GLib versions 2.31.8 and earlier, as well as several earlier versions including 1.x series.

  • How can CVE-2012-0039 be exploited?

    CVE-2012-0039 can be exploited by sending crafted input to applications that use the g_str_hash function, leading to predictable hash collisions.

  • Is CVE-2012-0039 a critical vulnerability?

    CVE-2012-0039 is not a critical vulnerability but can lead to significant performance issues due to CPU consumption in affected applications.
