Subject: Bug#839226: [PATCH] cups : SSL is vulnerable to POODLE
[Jessie]
Date: 2016-10-10 10:13

To: 839...@bugs.debian.org, debian-release@lists.debian.org

Hi again,
(dropping debian-lts from the loop, as this'd be for stable)
Le samedi, 1 octobre 2016, 06.34:28 h CEST Moritz Mühlenhoff a écrit :
> Have we removed protocols' support in {old,}stable before?.
We have done that on a case-by-case basis via point updates in the
past,
seems also fine here.
Here come:
- patch;
str4476-disable-sslv3-and-rc4-by-default.patch
- git commit series;
0001-Disable-SSLv3-and-RC4-by-default-to-address-POODLE-v.patch
0002-Refresh-patches.patch
0003-cups-1.7.5-11-deb8u2-Debian-release.patch
- and debdiff
cups_1.7.5-11+deb8u2.debdiff
Can I upload to jessie-security ?

Cheers,
OdyXDescription: Disable SSLv3 and RC4; implement SSLOptions.
This disables SSLv3 in cups. It also provides 2 configuration
options to reenable by specifying SSLOptions in the cupsd.conf
file. AllowSSL3 turns SSLv3 back on and AllowRC4 turns on just
the RC4 cypers.

+Description: Disable SSLv3 and RC4; implement SSLOptions.
+ This disables SSLv3 in cups. It also provides 2 configuration
+ options to reenable by specifying SSLOptions in the cupsd.conf
+ file. AllowSSL3 turns SSLv3 back on and AllowRC4 turns on just
+ the RC4 cypers.
