Severity: High Title: ncpfs: Buffer overflow in ncplogin and ncpmap Date: December 15, 2004 Bugs: #72820 ID: 200412-09

Synopsis ========
ncpfs is vulnerable to a buffer overflow that could lead to local execution of arbitrary code with elevated privileges.
Background ==========
ncpfs is a NCP protocol network filesystem that allows access to Netware services, for example to mount volumes of NetWare servers or print to NetWare print queues.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-fs/ncpfs < 2.2.5 >= 2.2.5
Description ===========
Karol Wiesek discovered a buffer overflow in the handling of the '-T' option in the ncplogin and ncpmap utilities, which are both installed as SUID root by default.
Impact ======
A local attacker could trigger the buffer overflow by calling one of these utilities with a carefully crafted command line, potentially resulting in execution of arbitrary code with root privileges.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All ncpfs users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-fs/ncpfs-2.2.5"
