Package: procmail
Version: 3.22-16
Severity: important
Hello,
There's a mailing list that makes procmail abort with
procmail: Skipped "toute requete administrative, contactez [email protected];
Liste geree par ezmlm/"
*** glibc detected *** procmail: double free or corruption (!prev): 0x0805cfe0
***
I could reduce it to the following .procmailrc
:0fw: spamassassin.lock
* < 256000
| /usr/bin/spamc
:0
* ^(List-Id|Mailing-List): \/[^<]*
IN/list/$MATCH/
and the attached mail. Running procmail -f Foo < mail-nvdafr-error
produces the abort. The gdb trace is as follows:

And this is indeed wrong: in writefolder() we allocate a string of size
Tmnate-linkfolder, and then concatenate() basically does *Tmnate = 0...
