Mandriva Security Advisory

MDVSA-2014:184: net-snmp

Updated net-snmp packages fix security vulnerabilities:

A remote denial-of-service flaw was found in the way snmptrapd handled
certain SNMP traps when started with the -OQ option. If an attacker
sent an SNMP trap containing a variable with a NULL type where an
integer variable type was expected, it would cause snmptrapd to crash
(CVE-2014-3565).

MDVSA-2014:191: perl-XML-DT

Updated perl-XML-DT package fixes security vulnerability:

The mkxmltype and mkdtskel scripts provided in perl-XML-DT allow
local users to overwrite arbitrary files via a symlink attack on a
/tmp/_xml_##### temporary file (CVE-2014-5260).

MDVSA-2014:186: bash

A flaw was found in the way Bash evaluated certain specially crafted
environment variables. An attacker could use this flaw to override or
bypass environment restrictions to execute shell commands. Certain
services and applications allow remote unauthenticated attackers to
provide environment variables, allowing them to exploit this issue
(CVE-2014-6271).

MDVSA-2014:190: bash

It was found that the fix for CVE-2014-6271 was incomplete, and
Bash still allowed certain characters to be injected into other
environments via specially crafted environment variables. An
attacker could potentially use this flaw to override or bypass
environment restrictions to execute shell commands. Certain
services and applications allow remote unauthenticated attackers to
provide environment variables, allowing them to exploit this issue
(CVE-2014-7169, CVE-2014-7186, CVE-2014-7187).

Additionally bash has been updated from patch level 37 to 48 using
the upstream patches at ftp://ftp.gnu.org/gnu/bash/bash-4.2-patches/
which resolves various bugs.

MDVSA-2014:187: curl

Updated curl packages fix security vulnerabilities:

In cURL before 7.38.0, libcurl can be fooled to both sending cookies
to wrong sites and into allowing arbitrary sites to set cookies for
others. For this problem to trigger, the client application must use
the numerical IP address in the URL to access the site (CVE-2014-3613).

In cURL before 7.38.0, libcurl wrongly allows cookies to be set for Top
Level Domains (TLDs), thus making them apply broader than cookies are
allowed. This can allow arbitrary sites to set cookies that then would
get sent to a different and unrelated site or domain (CVE-2014-3620).

MDVSA-2014:188: wireshark

Updated wireshark packages fix security vulnerabilities:

RTP dissector crash (CVE-2014-6421, CVE-2014-6422).

MEGACO dissector infinite loop (CVE-2014-6423).

Netflow dissector crash (CVE-2014-6424).

RTSP dissector crash (CVE-2014-6427).

SES dissector crash (CVE-2014-6428).

Sniffer file parser crash (CVE-2014-6429, CVE-2014-6430, CVE-2014-6431,
CVE-2014-6432).

MDVSA-2014:189: nss

A vulnerability has been discovered and corrected in Mozilla NSS:

Antoine Delignat-Lavaud, security researcher at Inria Paris in
team Prosecco, reported an issue in Network Security Services (NSS)
libraries affecting all versions. He discovered that NSS is vulnerable
to a variant of a signature forgery attack previously published
by Daniel Bleichenbacher. This is due to lenient parsing of ASN.1
values involved in a signature and could lead to the forging of RSA
certificates (CVE-2014-1568).

The updated NSPR packages have been upgraded to the latest 4.10.7
version.

The updated NSS packages have been upgraded to the latest 3.17.1
version which is not vulnerable to this issue.

Additionally the rootcerts package has also been updated to the latest
version as of 2014-08-05.
