The remote Scientific Linux host is missing one or more security
It was discovered that the glibc dynamic linker/loader did not handle
the $ORIGIN dynamic string token set in the LD_AUDIT environment
variable securely. A local attacker with write access to a file system
containing setuid or setgid binaries could use this flaw to escalate
their privileges. (CVE-2010-3847)
It was discovered that the glibc dynamic linker/loader did not perform
sufficient safety checks when loading dynamic shared objects (DSOs) to
provide callbacks for its auditing API during the execution of
privileged programs. A local attacker could use this flaw to escalate
their privileges via a carefully-chosen system DSO library containing
unsafe constructors. (CVE-2010-3856)
This update also fixes the following bugs :
- Previously, the generic implementation of the strstr()
and memmem() functions did not handle certain periodic
patterns correctly and could find a false positive
match. This error has been fixed, and both functions now
work as expected. (BZ#643341)
- The 'TCB_ALIGNMENT' value has been increased to 32 bytes
to prevent applications from crashing during symbol
resolution on 64-bit systems with support for Intel AVX
vector registers. (BZ#643343)
