that means that the info hasn't yet been populated in their database.
it was assigned on oss-security, and sometimes it takes a many days to
enter the database after that.

yes it is a 2008 issue, but it was only assigned an id a couple days
ago. they make date assignments based on discovery year; rather than
issue year.

[Message part 1 (text/plain, inline)]
tag 591515 + unreproducible
thanks

Hi,
Ubuntu bug-report was filed against 2.62 and contains a PoC/testcase.
Current squeeze and sid contain latest 2.64, and the aforementioned
testcase doesn't fail.

Moreover, as it seems to be an off-by-one error, I think it was fixed
in later versions, as ssmtp.c now accounts for it:

1385         if(vsnprintf(buf, (BUF_SZ - 1), format, ap) == -1) {
1386                 die("smtp_write() -- vsnprintf() failed");
1387         }

I'm tagging as unreproducible, as Anibal would certainly have more
knowledge about this than me to close it.

Cheers, Luca

Quoting the CVE description:

** DISPUTED ** The standardise function in Anibal Monsalve Salazar sSMTP
2.61 and 2.62 allows local users to cause a denial of service
(application exit) via an e-mail message containing a long line that
begins with a . (dot) character. NOTE: CVE disputes this issue because
it is solely a usability problem for senders of messages with certain
long lines, and has no security impact.

Downgrading.

Cheers,
Julien
