CWE-787

Description

Linux drivers/char/lp.c Out-of-Bounds Write. Due to a missing bounds check, and the fact that parport_ptr integer is static, a 'secure boot' kernel command line adversary (can happen due to bootloader vulns, e.g. Google Nexus 6's CVE-2016-10277, where due to a vulnerability the adversary has partial control over the command line) can overflow the parport_nr array in the following code, by appending many (>LP_NO) 'lp=none' arguments to the command line.

Affected configurations

• linux linux kernel (>= 2.6.12 < 3.2.91) • linux linux kernel (>= 3.3 < 3.10.106) • linux linux kernel (>= 3.11 < 3.16.46) • linux linux kernel (>= 3.17 < 3.18.55) • linux linux kernel (>= 3.19 < 4.1.41) • linux linux kernel (>= 4.2 < 4.4.70) • linux linux kernel (>= 4.5 < 4.9.30) • linux linux kernel (>= 4.10 < 4.11.3) • linux linux kernel 4.12 • debian debian linux 8.0
