1.  Bulletins Topics

    Sun announces the release of patches for Solaris(tm) 8, 7, and 2.6
    (SunOS(tm) 5.8, 5.7, and 5.6) which relate to buffer overflow
    vulnerabilities in libprint.so.2 and patches for Solaris(tm) 7
    and 2.6 which relate to a buffer overflow vulnerability in
    /usr/lib/lp/bin/netpr.

    Sun recommends that you install the patches listed in section 4
    immediately on systems running SunOS 5.8, 5.7, and 5.6.

2.  Who is Affected
	
    libprint.so.2:

	Vulnerable:		SunOS 5.7, 5.7_x86, 5.6, and 5.6_x86
    	Not vulnerable:		All other supported versions of SunOS.
    	
    /usr/lib/lp/bin/netpr:
	
    	Vulnerable:     	SunOS 5.8, 5.8_x86 5.7, 5.7_x86, 5.6,
    				and 5.6_x86
    	Not vulnerable:		All other supported versions of SunOS.	

3.  Understanding the Vulnerability

    The lpset utility sets printing configuration information in the
    system configuration databases. A buffer overflow vulnerability
    has been discovered in libprint.so.2 which may be exploited by a
    local attacker through lpset to gain root access. A buffer overflow
    vulnerability was also discovered in /usr/lib/lp/bin/netpr which
    may be exploited by a local attacker to gain root access.

4.  List of Patches
