BSD Portsxorg server -- _XkbSetCompatMap vulnerability
The X.Org project reports: CVE-2024-9632: Heap buffer Heap-based buffer overflow privilege escalation in _XkbSetCompatMap The _XkbSetCompatMap() function attempts to resize the `sym_interpret` buffer. However, It didn't update its size properly. It updated `num_si` only, without updating `size_si`. This may lead to local privilege escalation if the server is run as root or remote code execution (e.g. x11 over ssh).
Affected versions
- xorg-server < 21.1.14,1
- xwayland < 24.1.4,1
By system
0 still vulnerable, 2 fixed. Where VuXML applies (FreeBSD, DragonFly, FreeBSD's derivatives) a port is vulnerable while its version is in a range; pkgsrc says itself whether it lists a CVE of this advisory; OpenBSD and MidnightBSD keep no list this site reads, so their row is only an estimate: FreeBSD's ranges applied to upstream's version.
| System | Port | Version | State | Fixed |
|---|---|---|---|---|
| DragonFly | x11-servers/xwayland | 24.1.6,1 | fixed | |
| OpenBSD | wayland/xwayland | 24.1.14 | out of range, by version | |
| MidnightBSD | x11-servers/xwayland | 24.1.14,1 | out of range, by version | |
| FreeBSD | x11-servers/xwayland | 24.1.14,1 | fixed | (596 days after) |
