libgtop2 glibtop_get_proc_map_s() buffer overflow

libgtop2-glibtopbo (31522) The risk level is classified as HighHigh Risk

Description:

The libgtop2 library is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the glibtop_get_proc_map_s() function. By creating a specially-crafted process with an overly long path name, a local attacker could overflow a buffer and execute arbitrary code on the system with elevated privileges or cause the system to crash, if the attacker could convince a privileged user to run an application using the affected library.
