Subject: Bug#484352: procmail: Aborts because of corrupted string
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:
4 0xb7f6aef5 in raise () from /lib/i686/cmov/libc.so.6

valgrind says
==8314== Invalid write of size 1
==8314== at 0x804CEFA: concatenate (goodies.c:381)
==8314== by 0x804F5DB: writefolder (mailfold.c:217)
==8314== by 0x804A387: mainloop (procmail.c:884)
==8314== by 0x804B771: main (procmail.c:488)
==8314== Address 0x419bfa4 is 0 bytes after a block of size 84 alloc'd
==8314== at 0x4022AB8: malloc (vg_replace_malloc.c:207)
==8314== by 0x80546CF: tmalloc (robust.c:49)

==8314== by 0x804B771: main (procmail.c:488)
And this is indeed wrong: in writefolder() we allocate a string of size
Tmnate-linkfolder, and then concatenate() basically does *Tmnate = 0...
