I uploaded new packages for nginx which fixed the following security
problems:
CVE-2012-4929 - nginx -- vulnerable to CRIME SSL attack
The TLS protocol 1.2 and earlier, as used in Mozilla Firefox, Google
Chrome, Qt, and other products, can encrypt compressed data without
properly obfuscating the length of the unencrypted data, which allows
man-in-the-middle attackers to obtain plaintext HTTP headers by observing
length differences during a series of guesses in which a string in an HTTP
request potentially matches an unknown string in an HTTP header, aka a
"CRIME" attack.
Nginx < 1.2.2 is only vulnerable when built with openssl < 1.0.0
This has been corrected in upstream 1.2.2 version.
For the squeeze-backports distribution the problems have been fixed in
version
1.2.1-2.2~bpo+60+2
For Squeeze (stable) this was fixed in version
0.7.67-3+squeeze3
Wheezy (testing) and Sid (unstable) are not vulnerable to this security
issue.
