Synopsis ========
libgtop improperly handles filenames, possibly allowing for the execution of arbitrary code.
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 >=3D 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 ">=3Dgnome-base/libgtop-2.14.6"
References ==========
