Description John Helmert III archtester Gentoo Infrastructure gentoo-dev Security 2020-06-23 16:41:30 UTC
CVE-2020-14938:
An issue was discovered in map.c in FreedroidRPG 1.0rc2. It assumes lengths of data sets read from saved game files. It copies data from a file into a fixed-size heap-allocated buffer without size verification, leading to a heap-based buffer overflow.

CVE-2020-14939:
An issue was discovered in savestruct_internal.c in FreedroidRPG 1.0rc2. Saved game files are composed of Lua scripts that recover a game's state. A file can be modified to put any Lua code inside, leading to arbitrary code execution while loading.

Comment 2 John Helmert III archtester Gentoo Infrastructure gentoo-dev Security 2022-08-16 19:17:02 UTC
The first two issues are fixed by:

The third seems to be a much harder to fix design issue.

    games-rpg/freedroidrpg: add 1.0
    
    wrt #729326, this version adds lua sandboxing for save game
    handling (so guess can consider this fixed? or reasonable anyway).
