Package: rxvt-unicode
Version: 9.15-2
Severity: normal
Hi,
i use rxvt-unicode and was testing my perl module after the system got upgraded
to wheezy for some time now.
I use a module called send_to_all_vty which i have written.
This modules did work on squeeze without any problems.
The purpose of that module is to send the key input from one tab to all other
tabs so it helps on various system administration tasks, like when working on
multiple systems via ssh.
Unfortunately it appears that rxvt-unicode now segfaults.
dmesg output:
rxvt[4161]: segfault at 7fffe2075ff8 ip 00007f4c0155c34c sp 00007fffe2076000

This may also lead to a buffer overflow vulnerability.
