X.Org X11 BDF font buffer overflow
| xorg-bdf-font-bo (33417) |  High Risk |
Description:
X.Org X11 is vulnerable to a heap-based buffer overflow, caused by an integer overflow vulnerability in the parsing of BDF fonts. By creating a specially-crafted BDF font file and persuading a victim to open the file, a local attacker could overflow a buffer and execute arbitrary code on the system with ROOT privileges or cause the system to crash.
