Background ========= libgtop facilitates the libgtop_daemon, which is used by GNOME to obtain information about remote systems. Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 gnome-base/libgtop < 2.14.6 > = 2.14.6 Description ========== Liu Qishuai discovered that glibtop_get_proc_map_s() in sysdeps/linux/procmap.c does not properly allocate memory for storing a filename, allowing certain filenames to cause the buffer to overflow on the stack. Impact ===== By tricking a victim into executing an application that uses the libgtop library (e.g. libgtop_daemon or gnome-system-monitor), a local attacker could specify a specially crafted filename to be used by libgtop causing a buffer overflow and possibly execute arbitrary code with the rights of the user running the application. Workaround ========= There is no known workaround at this time. Resolution ========= All libgtop users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=gnome-base/libgtop-2.14.6" References ========= [ 1 ] CVE-2007-0235 https://www.cve.org/CVERecord?id=CVE-2007-0235 Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200701-17 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. Any security concerns should be addressed to
libgtop_daemon runs as user nobody both bugs could be usedto gain access as the nobody user to a system running libgtop_daemon.. ------------------------------------------------------------------------ Debian Security Advisory DSA-098-1
