CVE-2013-0914: The flush_signal_handlers function in kernel/signal.c in the Linux kernel before 3.8.4 preserves the value...

The flush_signal_handlers function in kernel/signal.c in the Linux kernel before 3.8.4 preserves the value of the sa_restorer field across an exec operation, which makes it easier for local users to bypass the ASLR protection mechanism via a crafted application containing a sigaction system call.

Security readout for executives and security teams

CVE-2013-0914 is an old Linux kernel flaw that could make ASLR less effective for a local user. It is not described as a remote compromise by the provided sources. Business urgency is highest for legacy Linux systems where untrusted users or workloads can run local code. Exposure is most likely on legacy Linux systems running kernels before the upstream 3.8.4 fix or affected vendor kernels before their 2013 advisories. Internet-facing status alone is not the key factor; local account or local code execution matters more. Moderate priority for normal estates, higher for legacy multi-user or shared compute environments. This is old and local-only in the supplied evidence, but it weakens a core exploitation barrier and should not remain on supported systems. Mitigation focus: Update affected Linux kernels through the relevant vendor security advisory.; Use Linux kernel 3.8.4 or a vendor-backported fixed kernel where applicable.; Prioritize shared systems and hosts running untrusted local workloads..
