kernel: x86_64: ptrace: sysret to non-canonical address

It was found that the Linux kernel's ptrace subsystem allowed a traced process' instruction pointer to be set to a non-canonical memory address without forcing the non-sysret code path when returning to user space. A local, unprivileged user could use this flaw to crash the system or, potentially...

DEBIAN-CVE-2014-4699

The Linux kernel before 3.15.4 on Intel processors does not properly restrict use of a non-canonical value for the saved RIP address in the case of a system call that does not use IRET, which allows local users to leverage a race condition and gain privileges, or cause a denial of service double...

CVE-2014-4699

CVE-2014-4699 affects the Linux kernel prior to 3.15.4 on Intel CPUs: a non-canonical saved RIP value in system calls that do not use IRET can be exploited via ptrace and fork to escalate privileges or trigger a denial of service (double fault). Multiple connected advisories (e.g., MiracleLinux A...
