Detailsinfo

A vulnerability was found in GNOME GLib up to 2.26.0. It has been rated as problematic. Affected by this issue is the function hash. The manipulation with an unknown input leads to a cryptographic issue vulnerability. Using CWE to declare the problem leads to CWE-310. Impacted is availability. CVE summarizes:

** 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.

The weakness was published 01/14/2012 as Bug 772720 as not defined bug report (Bugzilla). The advisory is available at bugzilla.redhat.com. This vulnerability is handled as CVE-2012-0039 since 12/07/2011. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1600 by the MITRE ATT&CK project.
