Title:
stack smashing attack detected in bash host tab completion
Status in glibc package in Ubuntu:
Confirmed
Status in glibc source package in Focal:
Fix Committed
Bug description:
Hello, this is a speculative bug report at best.
In some long-lived bash terminals, tab completion of hostnames on ping
or ssh commands is printing the glibc stack smashing attempt error
message:
$ ping goog*** stack smashing detected ***: terminated
^C
$ ssh local*** stack smashing detected ***: terminated
host ^C
I installed the glibc update 2.31-0ubuntu9.3
https://lists.ubuntu.com/archives/focal-changes/2021-April/024256.html
earlier today. Shells started *after* this update work fine. Shells
started before this update show this behaviour.
