Gentoo Linux Security Advisory GLSA 200711-33
Severity: Low Title: nss_ldap: Information disclosure Date: November 25, 2007 Bugs: #198390 ID: 200711-33
Synopsis ======== A race condition might lead to theft of user credentials or information disclosure in services using nss_ldap. Background ========== nss_ldap is a Name Service Switch module which allows 'passwd', 'group' and 'host' database information to be pulled from LDAP. Affected packages ================= Package / Vulnerable / Unaffected 1 sys-auth/nss_ldap < 258 >= 258 Description =========== Josh Burley reported that nss_ldap does not properly handle the LDAP connections due to a race condition that can be triggered by multi-threaded applications using nss_ldap, which might lead to requested data being returned to a wrong process. Impact ====== Remote attackers could exploit this race condition by sending queries to a vulnerable server using nss_ldap, possibly leading to theft of user credentials or information disclosure (e.g. Dovecot returning wrong mailbox contents). Workaround ========== There is no known workaround at this time. Resolution ========== All nss_ldap users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=sys-auth/nss_ldap-258" References ========== [ 1 ] CVE-2007-5794 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5794 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200711-33.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.

#28 | fixed | Nagios should check for nearly-expired certificates | quentin | broder |
Description |
"We should set up Nagios to check for certificates that are about to expire (say within a week), so that we don't get caught by surprise again. Anders" (Taken from RT #469122) |

#26 | fixed | upgrade PCRE, if it's old enough to be vulnerable | quentin | price |
Description |
Some version of PCRE is vulnerable. Are we affected? Was https://help.mit.edu/?q=530046. Quentin forwarded the following email: Date: Tue, 20 Nov 2007 22:44:46 +0100 From: Pierre-Yves Rofes <py@…> To: gentoo-announce@… Cc: full-disclosure@…, bugtraq@…, security-alerts@… Subject: [gentoo-announce] [ GLSA 200711-30 ] PCRE: Multiple vulnerabilities Hash: SHA1
Gentoo Linux Security Advisory GLSA 200711-30
Severity: Normal Title: PCRE: Multiple vulnerabilities Date: November 20, 2007 Bugs: #198198 ID: 200711-30
Synopsis ======== PCRE is vulnerable to multiple buffer overflow and memory corruption vulnerabilities, possibly leading to the execution of arbitrary code. Background ========== PCRE is a library providing functions for Perl-compatible regular expressions. Affected packages ================= Package / Vulnerable / Unaffected 1 dev-libs/libpcre < 7.3-r1 >= 7.3-r1 Description =========== Tavis Ormandy (Google Security) discovered multiple vulnerabilities in PCRE. He reported an error when processing "\Q\E" sequences with unmatched "\E" codes that can lead to the compiled bytecode being corrupted (CVE-2007-1659). PCRE does not properly calculate sizes for unspecified "multiple forms of character class", which triggers a buffer overflow (CVE-2007-1660). Further improper calculations of memory boundaries were reported when matching certain input bytes against regex patterns in non UTF-8 mode (CVE-2007-1661) and when searching for unmatched brackets or parentheses (CVE-2007-1662). Multiple integer overflows when processing escape sequences may lead to invalid memory read operations or potentially cause heap-based buffer overflows (CVE-2007-4766). PCRE does not properly handle "\P" and "\P{x}" sequences which can lead to heap-based buffer overflows or trigger the execution of infinite loops (CVE-2007-4767), PCRE is also prone to an error when optimizing character classes containing a singleton UTF-8 sequence which might lead to a heap-based buffer overflow (CVE-2007-4768). Chris Evans also reported multiple integer overflow vulnerabilities in PCRE when processing a large number of named subpatterns ("name_count") or long subpattern names ("max_name_size") (CVE-2006-7227), and via large "min", "max", or "duplength" values (CVE-2006-7228) both possibly leading to buffer overflows. Another vulnerability was reported when compiling patterns where the "-x" or "-i" UTF-8 options change within the pattern, which might lead to improper memory calculations (CVE-2006-7230). Impact ====== An attacker could exploit these vulnerabilities by sending specially crafted regular expressions to applications making use of the PCRE library, which could possibly lead to the execution of arbitrary code, a Denial of Service or the disclosure of sensitive information. Workaround ========== There is no known workaround at this time. Resolution ========== All PCRE users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/libpcre-7.3-r1" References ========== [ 1 ] CVE-2006-7227 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-7227 [ 2 ] CVE-2006-7228 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-7228 [ 3 ] CVE-2006-7230 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-7230 [ 4 ] CVE-2007-1659 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-1659 [ 5 ] CVE-2007-1660 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-1660 [ 6 ] CVE-2007-1661 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-1661 [ 7 ] CVE-2007-1662 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-1662 [ 8 ] CVE-2007-4766 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4766 [ 9 ] CVE-2007-4767 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4767 [ 10 ] CVE-2007-4768 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4768 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200711-30.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
