CVE-2012-0039

HIGHCVSS 7.5/10EPSS 2.16%

Last modified

CVE-2012-0039 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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.. EPSS estimates a 2.16% chance of exploitation in the next 30 days.
