Novell · Novell Client · CVE-2013-3697
**Name of the Vulnerable Software and Affected Versions**
Novell Client versions 4.91 SP5
Novell Client 2 versions SP2, SP3
**Description**
The issue is related to an integer overflow in kernel drivers, specifically NWFS.SYS and NCPL.SYS, which might allow local users to gain privileges. This can be achieved via a crafted 0x1439EB IOCTL call.
**Recommendations**
For Novell Client version 4.91 SP5, consider restricting access to the NWFS.SYS kernel driver until a patch is available.
For Novell Client 2 versions SP2 and SP3, consider disabling the NCPL.SYS kernel driver as a temporary workaround to minimize the risk of exploitation.
