There is no fixed version for linux-pam/linux-pam.
Overview
Affected versions of this package are vulnerable to Information Exposure due to the storage of secret information in memory. An attacker can access sensitive data by sending characters to the standard input (stdin) of the victim program, which triggers speculative execution through branch prediction to execute an ROP chain.
Note: According to the contributors, this attack is difficult to pull of:
Attacker needs to find a gadget chain in the mapped-in executable memory of the victim.
Attacker needs to trigger TLB entries to be prefetched to win the race and fit the transient operations in the miss-speculation window.
Attacker needs to tweak the attack to break ASLR. This they also can do using Spectre as well.
