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" References ========= [ 1 ] Full Disclosure Advisory [ 2 ]CAN-2004-1079 https://www.cve.org/CVERecord?id=CAN-2004-1079 Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200412-09 Concerns? ======== Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
