Vulnerability Assessment Details

[GLSA-200701-17] libgtop: Privilege escalation

Vulnerability Assessment Summary
libgtop: Privilege escalation

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200701-17
(libgtop: Privilege escalation)


Liu Qishuai discovered that glibtop_get_proc_map_s() in
sysdeps/linux/procmap.c does not properly allocate memory for storing a
filename, permiting 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.
