1.  Bulletin Topics

    Sun announces the release of patches for Solaris(tm) 7 and 2.6 (SunOS(tm)
    5.7 and 5.6) which relate to a buffer overflow vulnerability involving
    the LC_MESSAGES environment variable.

    Sun recommends that you install the patches listed in section 4
    immediately on systems running SunOS 5.7 and 5.6.


2.  Who is Affected
  
    Vulnerable:     SunOS 5.7, 5.7_x86, 5.6, 5.6_x86.

    Not vulnerable: All other supported versions of SunOS.


3.  Understanding the Vulnerability

    In libc, the LC_MESSAGES environment variable affects the behavior of
    messaging functions.  A vulnerability exists where a buffer overflow
    could be exploited to gain root access.  The patches listed in this
    bulletin address both libc and the ufsrestore and rcp binaries which
    are statically linked against libc.
