The remote Scientific Linux host is missing one or more security
Security Fix(es) :
- A flaw was found in the way memory was being allocated
on the stack for user space binaries. If heap (or
different memory region) and stack memory regions were
adjacent to each other, an attacker could use this flaw
to jump over the stack guard gap, cause controlled
memory corruption on process stack or the adjacent
memory region, and thus increase their privileges on the
system. This is glibc-side mitigation which blocks
processing of LD_LIBRARY_PATH for programs running in
secure-execution mode and reduces the number of
allocations performed by the processing of LD_AUDIT,
LD_PRELOAD, and LD_HWCAP_MASK, making successful
exploitation of this issue more difficult.
