| Description |
Installing the accountadm package causes the signup user to be deleted. Looking at the spec file, I'm not entirely sure why. |

| #21 | fixed | upgrade out of Rails vulnerabilities | mitchb | price |
| Description |
We have 1.2.3 and some older Rails installed, and 1.2.3 is vulnerable. 1.2.5 is fixed. Some users may be using 1.2.3 (we also have 2.something), so we should get them upgraded. Hopefully this just means installing 1.2.5 and deleting 1.2.3; if these were, eg, Python versions, that'd be true. We don't know enough about Rails to know if it'll be that easy, or require changes to users' scripts.

Background ========== Ruby on Rails is a free web framework used to develop database-driven web applications. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-ruby/rails < 1.2.5 >= 1.2.5 Description =========== candlerb found that ActiveResource, when processing responses using the Hash.from_xml() function, does not properly sanitize filenames (CVE-2007-5380). The session management functionality allowed the "session_id" to be set in the URL (CVE-2007-5380). BCC discovered that the to_json() function does not properly sanitize input before returning it to the user (CVE-2007-3227). Impact ====== Unauthenticated remote attackers could exploit these vulnerabilities to determine the existence of files or to read the contents of arbitrary XML files; conduct session fixation attacks and gain unauthorized access; and to execute arbitrary HTML and script code in a user's browser session in context of an affected site by enticing a user to browse a specially crafted URL. Workaround ========== There is no known workaround at this time. Resolution ========== All Ruby on Rails users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-ruby/rails-1.2.5" References ========== [ 1 ] CVE-2007-3227 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3227 [ 2 ] CVE-2007-5379 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5379 [ 3 ] CVE-2007-5380 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5380 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200711-17.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.

| #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.
