SECUNIA ADVISORY ID:
SA30667
VERIFY ADVISORY:
http://secunia.com/advisories/30667/
CRITICAL:
Highly critical
IMPACT:
Exposure of sensitive information, System access
WHERE:
From remote
SOFTWARE:
Novell iPrint Client 4.x
http://secunia.com/product/14992/
Novell iPrint Client for Windows Vista 5.x
http://secunia.com/product/19621/
DESCRIPTION:
Secunia Research has discovered multiple vulnerabilities in Novell
iPrint Client, which can be exploited by malicious people to gain
knowledge of potentially sensitive information or compromise a user's
system.
1) A boundary error in the Novell iPrint ActiveX control (ienipp.ocx)
when handling the "GetDriverFile()" method can be exploited to cause a
stack-based buffer overflow by passing an overly long string as the
third argument.
2) Two boundary errors in the Novell iPrint ActiveX control
(ienipp.ocx) when constructing URIs based on input to the
"GetPrinterURLList()" and "GetPrinterURLList2()" methods can be
exploited to cause limited stack-based buffer overflows via an overly
long string passed as the 1st argument.
3) A boundary error in the Novell iPrint ActiveX control (ienipp.ocx)
when handling the "GetFileList()" method can be exploited to cause a
heap-based buffer overflow via an overly long argument.
4) Various boundary errors in nipplib.dll when e.g. creating a server
reference or interpreting a URI can be exploited to cause stack-based
and heap-based buffer overflows by e.g. passing an overly long string
as argument to the "GetServerVersion()", "GetResourceList()", or
"DeleteResource()" methods provided by the Novell iPrint ActiveX
control (ienipp.ocx).
5) Boundary errors in the Novell iPrint ActiveX control (ienipp.ocx)
when constructing URIs based on input to the "UploadPrinterDriver()"
and "UploadResource()" methods can be exploited to cause a heap-based
buffer overflow and limited stack-based buffer overflow via an overly
long, specially crafted "uploadPath" argument.
6) A boundary error in the Novell iPrint ActiveX control (ienipp.ocx)
when copying "target-frame" option values passed to the
"ExecuteRequest()" method can be exploited to cause a limited
stack-based buffer overflow via an overly long "target-frame" option
value.
7) The insecure "GetFileList()" method returns a list of images
(".jpg", ".jpeg", ".gif", and ".bmp") in a directory specified as
argument to the method, which can be exploited to gain knowledge of
any image file names in arbitrary directories on a user's system.
This includes e.g. the user's "My Pictures" folder without knowledge
of the user's username.
8) A boundary error in the Novell iPrint ActiveX control (ienipp.ocx)
when handling the "UploadResource()" method can be exploited to cause
a stack-based buffer overflow by passing an overly long string as the
7th argument.
9) Three boundary errors in nipplib.dll within the
"IppGetDriverSettings()" function can be exploited to cause
stack-based buffer overflows by passing an overly long string as the
2nd, 3rd, or 4th argument of the "GetDriverSettings()" method
provided by Novell iPrint ActiveX control (ienipp.ocx).
10) A boundary error in the Novell iPrint ActiveX control
(ienipp.ocx) when handling the "UploadResourceToRMS" method can be
exploited to cause a stack-based buffer overflow by passing an overly
long string as the 8th argument.
The vulnerabilities have been confirmed in versions 4.36 and 5.04.
Other versions may also be affected.
SOLUTION:
Update to version 5.06, which seems to address all vulnerabilities
except #6.

A fix for version 4.x is not currently available.
