Description Leonard den Ottolander 2005-02-25 22:02:13 UTC 
http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-0373

Affects RHEL 3 and 4. Please check whether it affects RHEL 2.1.
Comment 1 Leonard den Ottolander 2005-02-25 22:42:08 UTC

Comment 2 Leonard den Ottolander 2005-02-25 22:55:15 UTC 
Does not affect RHEL 4 (2.1.19). Does affect RHEL 3 (2.1.18). Not sure
about RHEL 2.1.
Comment 3 Leonard den Ottolander 2005-02-28 22:06:37 UTC 
https://bugzilla.andrew.cmu.edu/cgi-bin/cvsweb.cgi/src/sasl/plugins/digestmd5.c#rev1.171
:

        * plugins/digestmd5.c: Fix potential buffer overflow, call
          add_to_challenge in 2 more places (Alexey Melnikov

So indeed the issue seems to be the sprintf(text->outbuf)s, not the
quoting.
Comment 4 Leonard den Ottolander 2005-03-01 22:02:40 UTC 
Alexey Melnikov verified that this issue only exists in rev 1.170 of
digestmd5.c. Official releases are hence not vulnerable.

Closing NOTABUG.
