All supported architectures
Cube is vulnerable to a buffer overflow, invalid memory access and remote
client crashes, possibly leading to a Denial of Service or remote code
Cube is an open source first person shooter game engine supporting
multiplayer via LAN or internet.
Luigi Auriemma reported that Cube is vulnerable to a buffer
overflow in the sgetstr() function (CVE-2006-1100) and that the
sgetstr() and getint() functions fail to verify the length of the
supplied argument, possibly leading to the access of invalid memory
regions (CVE-2006-1101). Furthermore, he discovered that a client
crashes when asked to load specially crafted mapnames (CVE-2006-1102).
A remote attacker could exploit the buffer overflow to execute
arbitrary code with the rights of the user running cube. An attacker
could also exploit the other vulnerabilities to crash a Cube client or
server, resulting in a Denial of Service.
Play solo games or restrict your multiplayer games to trusted
Upstream stated that there will be no fixed version of Cube, thus
the Gentoo Security Team decided to hardmask Cube for security reasons.
All Cube users are encouraged to uninstall Cube:
