Hello,
just tried to reproduce the issue I think the problem here is just
with a short time format ('04:00').
In that case 5 characters are copied by strncpy in parse_timestamp
to timestamp variable. Unfortunately these 5 characters do not contain
the termination, therefore the following strcat
Package: sysstat
Version: 11.4.3-1
Severity: normal
The program /usr/bin/sar shows a buffer overflow if I use option either -s or
-e to specify start or end time.
[whr@ZONGYI-TMACH]:[20]:[~]:$ sar -s 04:00
*** buffer overflow detected ***: sar terminated
=== Backtrace: =
2 matches
