[asterisk-bugs] [JIRA] (ASTERISK-21854) possible memory corruption when using long Asterisk-version strings

[Rusty Newton (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-21854?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=207001#comment-207001 ] 

Rusty Newton commented on ASTERISK-21854:
-----------------------------------------

Using the same string: "11.4.0 890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890"

I consistently get the following output on a -r connection to asterisk:
{noformat}
Connected to Asterisk 11.4.0 890123456789012345678901234567890123456789012345678901234567 currently running on ubuntu (pid = 13048)
890123456789012345678901234567890
{noformat}

Looks like an issue occurring only where the version string is displayed when connecting with a remote console.

Some of the other places you can see the version string:

{noformat}
 asterisk -V

> When using a long version string in file ".version", the presented string when connecting to the Asterisk CLI looks corrupted. See following example: the string printed directly is correct, the "Connected to" string (which shows the version received via the socket from the server) is broken:
