ncpfs: Buffer overflow in ncplogin and ncpmap

ncpfs: Buffer overflow in ncplogin and ncpmap ncpfs is vulnerable to a buffer overflow that could lead to local execution of arbitrary code with elevated privileges. ncpfs 2004-12-15 2004-12-15 72820 local 2.2.5 2.2.5

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.

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.

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.

There is no known workaround at this time.

All ncpfs users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-fs/ncpfs-2.2.5"
