(Red Hat Issues Fix) CUPS Heap Overflow in 'texttops' Lets Remote Users Execute Arbitrary Code
SecurityTracker Alert ID:  1021036
SecurityTracker URL:  http://securitytracker.com/id/1021036
CVE Reference:   CVE-2008-3640, CVE-2009-0577   (Links to External Site)
Updated:  Feb 19 2009
Original Entry Date:  Oct 10 2008
Impact:   Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): prior to 1.3.9
Description:   A vulnerability was reported in CUPS. A remote user can execute arbitrary code on the target system.

A remote user can send a specially crafted text file to the CUPS service to trigger a heap overflow and execute arbitrary code on the target system. The code will run with the 'lp' user privileges.

The vulnerability resides in the Text-to-PostScript "texttops" filter WriteProlog() function.

regenrecht reported this vulnerability.

Impact:   A remote user can execute arbitrary code on the target system.
Solution:   On February 19, 2009, Red Hat has released a revised fix. The original fix (described in RHSA-2008-0937) did not properly correct the flaw on Red Hat Enterprise Linux 3. The incorrect fix has been assigned CVE-2009-0577.

The original Red Hat advisory is available at:

3. Description:

The Common UNIX Printing System (CUPS) provides a portable printing layer
for UNIX(R) operating systems.

A buffer overflow flaw was discovered in the SGI image format decoding
routines used by the CUPS image converting filter "imagetops". An attacker
could create a malicious SGI image file that could, possibly, execute
arbitrary code as the "lp" user if the file was printed. (CVE-2008-3639)

An integer overflow flaw leading to a heap buffer overflow was discovered
in the Text-to-PostScript "texttops" filter. An attacker could create a
malicious text file that could, possibly, execute arbitrary code as the
"lp" user if the file was printed. (CVE-2008-3640)

An insufficient buffer bounds checking flaw was discovered in the
HP-GL/2-to-PostScript "hpgltops" filter. An attacker could create a
malicious HP-GL/2 file that could, possibly, execute arbitrary code as the
"lp" user if the file was printed. (CVE-2008-3641)

Red Hat would like to thank regenrecht for reporting these issues.

All CUPS users are advised to upgrade to these updated packages, which
contain backported patches to resolve these issues.
