An integer wraparound was discovered in glib due to passing a 64 bit sized value to function g_memdup() which accepts a 32 bits number as argument. An attacker may abuse this flaw when an application linked against the glib library uses g_bytes_new() function or possibly other functions that use g_memdup() underneath and accept a 64 bits argument as size. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
