CVE-2014-3534: Debian Linux

High severity, CVSS 7.2. EPSS: 0.5% chance of exploitation in the next 30 days.

arch/s390/kernel/ptrace.c in the Linux kernel before 3.15.8 on the s390 platform does not properly restrict address-space control operations in PTRACE_POKEUSR_AREA requests, which allows local users to obtain read and write access to kernel memory locations, and consequently gain privileges, via a crafted application that makes a ptrace system call.

Affected products

• Debian Debian Linux: version 7.0 only
• Linux Linux Kernel: before 3.2.62 (fixed in 3.2.62); from 3.3, before 3.4.101 (fixed in 3.4.101); from 3.5, before 3.10.51 (fixed in 3.10.51); from 3.11, before 3.12.27 (fixed in 3.12.27); from 3.13, before 3.14.15 (fixed in 3.14.15); from 3.15, before 3.15.8 (fixed in 3.15.8)
