A collocated user can observe the process of creating a temporary sub directory in the shared temporary directory and race to complete the creation of the temporary subdirectory. If the attacker wins the race then they will have read and write permission to the subdirectory used to unpack web applications, including their WEB-INF/lib jar files and JSP files. If any code is ever executed out of this temporary directory, this can lead to a local privilege escalation vulnerability.",

However, if the data in GBytes is taken through functions such as g_bytes_unref_to_data or g_bytes_unref_to_array it might be possible to have out-of-bounds writes due to the wrongly reported size of the buffer.\n\nApplications that use g_memdup to duplicate memory with user-controlled sizes should pay extra attention to the fact that g_memdup accepts a guint size instead of gsize. Thus directly passing a gsize value to g_memdup may results in integer truncation, allocating a buffer smaller than expected.",
