CVE-2015-3276 [HIGH] CWE-682 openldap: incorrect multi-keyword mode cipherstring parsing
openldap: incorrect multi-keyword mode cipherstring parsing
The nss_parse_ciphers function in libraries/libldap/tls_m.c in OpenLDAP does not properly parse OpenSSL-style multi-keyword mode cipher strings, which might cause a weaker than intended cipher to be used and allow remote attackers to have unspecified impact via unknown vectors.
A flaw was found in the way OpenLDAP parsed OpenSSL-style cipher strings. As a result, OpenLDAP could potentially use ciphers that were not intended to be enabled.
Statement: This issue does not affect the version of openldap package as shipped with Red Hat Enterprise Linux 5.
This issue does not affect the version of openldap package as shipped with Red Hat Enterprise Linux 8.

CVE-2015-3276 [HIGH] CVE-2015-3276 openldap: incorrect multi-keyword mode cipherstring parsing
CVE-2015-3276 openldap: incorrect multi-keyword mode cipherstring parsing
The openldap (for NSS) emulation of the openssl cipherstring parsing code
incorrectly implements the multi-keyword mode.
As a consequence anyone using a combination like:

will not get the expected set of ciphers

CVE-2015-3277 mod_nss: incorrect multi-keyword mode cipherstring parsing
bugzilla·2015-07-01·CVSS 7.5
CVE-2015-3277 [HIGH] CVE-2015-3277 mod_nss: incorrect multi-keyword mode cipherstring parsing
CVE-2015-3277 mod_nss: incorrect multi-keyword mode cipherstring parsing
It was reported that mod_nss is vulnerable to the issue similar to CVE-2015-3276, where incorrect parsing of multi-keyword cipherstring can lead to an unexpected ciphers list advertising.
Acknowledgements:
Red Hat would like to thank Martin Poole of Software Maintenance Engineering group for reporting this issue.
Discussion:
The vulnerable code was added to mod_nss via the following commit:
https://git.fedorahosted.org/cgit/mod_nss.git/commit/?id=2d1650900f4d47dc43400d826c0f7e1a7c5229b8
And it was released as mod_nss-1.10.11
Therefore this does not affect the version of mod_nss package shipped with Red Hat Enterprise Linux 5, 6 and 7.
