3. Description:
The glibc packages provide the standard C libraries (libc), POSIX thread
libraries (libpthread), standard math libraries (libm), and the name
service cache daemon (nscd) used by multiple programs on the system.
Without these libraries, the Linux system cannot function correctly.
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. (CVE-2017-1000366)
Red Hat would like to thank Qualys Research Labs for reporting this issue.
4. Solution:
For details on how to apply this update, which includes the changes
described in this advisory, refer to:
https://access.redhat.com/articles/11258
For the update to take effect, all services linked to the glibc library
must be restarted, or the system rebooted.
5. Bugs fixed (https://bugzilla.redhat.com/):
1452543 - CVE-2017-1000366 glibc: heap/stack gap jumping via unbounded stack allocations

3. Description:
The glibc packages provide the standard C libraries (libc), POSIX thread
libraries (libpthread), standard math libraries (libm), and the name
service cache daemon (nscd) used by multiple programs on the system.
Without these libraries, the Linux system cannot function correctly.
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. (CVE-2017-1000366)
Red Hat would like to thank Qualys Research Labs for reporting this issue.
4. Solution:
For details on how to apply this update, which includes the changes
described in this advisory, refer to:
https://access.redhat.com/articles/11258
For the update to take effect, all services linked to the glibc library
must be restarted, or the system rebooted.
5. Bugs fixed (https://bugzilla.redhat.com/):
1452543 - CVE-2017-1000366 glibc: heap/stack gap jumping via unbounded stack allocations

3. Description:
The glibc packages provide the standard C libraries (libc), POSIX thread
libraries (libpthread), standard math libraries (libm), and the name
service cache daemon (nscd) used by multiple programs on the system.
Without these libraries, the Linux system cannot function correctly.
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. (CVE-2017-1000366)
Red Hat would like to thank Qualys Research Labs for reporting this issue.
4. Solution:
For details on how to apply this update, which includes the changes
described in this advisory, refer to:
https://access.redhat.com/articles/11258
For the update to take effect, all services linked to the glibc library
must be restarted, or the system rebooted.
5. Bugs fixed (https://bugzilla.redhat.com/):
1452543 - CVE-2017-1000366 glibc: heap/stack gap jumping via unbounded stack allocations
