A vulnerability has been discovered in sudosh3, which can be exploited by malicious, local users to gain escalated privileges.
The vulnerability is caused due to a boundary error within the "replay()" function in src/replay.c, which can be exploited to cause a stack-based buffer overflow by tricking another user (usually with "root" privileges) into replaying a specially crafted recorded session.
The vulnerability is confirmed in version 3.2.0. Other versions may also be affected,
Solution: Do not replay untrusted recorded sessions.
