Problem found by Michal Zalewski. Note: an MTA that is not patched might be vulnerable to data that it receives from untrusted sources, which includes DNS. To provide partial protection to internal, unpatched sendmail MTAs, 8.12.9 changes by default (char)0xff to (char)0x7f in headers etc. To turn off this conversion compile with -DALLOW_255 or use the command line option -d82.101. To provide partial protection for internal, unpatched MTAs that may be performing 7->8 or 8->7 bit MIME conversions, the default for MaxMimeHeaderLength has been changed to 2048/1024. Note: this does have a performance impact, and it only protects against frontal attacks from the outside. To disable the checks and return to pre-8.12.9 defaults, Changed files: sendmail.spec -> 1.121 --- diff --git a/sendmail.spec b/sendmail.spec index e472eb5..bdd5fbc 100644 --- a/sendmail.spec +++ b/sendmail.spec @@ -16,7 +16,7 @@ Summary(ru): Summary(tr): Elektronik posta hizmetleri sunucusu Summary(uk): ðÏÛÔÏ×ÉÊ ÔÒÁÎÓÐÏÒÔÎÉÊ ÁÇÅÎÔ sendmail Name: sendmail -Version: 8.12.8 +Version: 8.12.9 Release: 1 License: BSD Group: Networking/Daemons
