PERTAIN_TOProblem

takes user-controlled PostScript parameters (upWriteComponentCommands, upYMoveCommand) and passes them DIRECTLY as the format string argument — Ghostscript 'uniprint' device (devices/gdevupd.c). Tension: Attacker-supplied %s/%x/%n conversion specifiers yield arbitrary read & write primitives, bypassing -dSAFER and leading to RCE on a victim that renders a malicious PostScript/PDF. Outcome: upWriteComponentCommands, upYMoveCommand) and passes them DIRECTLY as the format string argument to gp_fprintf and gs_snprintf inside upd_wrtrtl (lines 7021, 7028, 7049, 7053) and similar writer functions.

PERTAIN_TOReport

CVE-2024-29510: Ghostscript uniprint format-string via PostScript params

PERTAIN_TOSolution

Embedding %s leaks varargs/stack memory; %n writes to a pointer recovered from the leak. — upd_wrtrtl at line 6994. Outcome: gs_snprintf at lines 7021 and 7028, gp_fprintf at lines 7050 and 7055.
