CVE-2017-10966
This would then result in use-after-free conditions on each access of the hash table.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.94%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
An issue was discovered in Irssi before 1.0.4. While updating the internal nick list, Irssi could incorrectly use the GHashTable interface and free the nick while updating it. This would then result in use-after-free conditions on each access of the hash table.
