Remote command execution via unquoted delta paths
Published Feb 24, 2020 · Updated Aug 5, 2024
Command injection in pacman before 5.2 allows remote attackers to execute arbitrary commands via a crafted database and delta file. The apply_deltas() function interpolates attacker-controlled delta paths into an xdelta3 shell command and invokes it through system() without shell-safe argument separation. Exploitation requires unsigned databases, the non-default UseDelta feature, and retrieval of attacker-controlled database and delta data.
