Linux kernel dvd_read_bca() buffer overflow
| linux-dvdreadbca-bo (27579) |  High Risk |
Description:
The Linux kernel DVD handling code in drivers/cdrom/cdrom.c is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the dvd_read_bca() function. By creating a malicious USB storage device that assigns an incorrect length variable, a local attacker could overflow a buffer and execute arbitrary code on the system with elevated privileges.
