--- title: "CVE-2012-1581\n | Ubuntu" description: Ubuntu is an open source software operating system that runs from the desktop, to the cloud, to all your internet connected things. url: https://ubuntu.com/security/CVE-2012-1581?format=md keywords: index, follow --- # CVE-2012-1581 Publication date 9 September 2012 Last updated 24 July 2024 --- Ubuntu priority **Low** [Why this priority?](https://ubuntu.com/security/cves/about#priority ) Toggle side navigation ## Description MediaWiki 1.17.x before 1.17.3 and 1.18.x before 1.18.2 uses weak random numbers for password reset tokens, which makes it easier for remote attackers to change the passwords of arbitrary users. Any extension developers using mt\_rand() to generate random numbers in contexts where security is required are encouraged to instead make use of the MWCryptRand class introduced with this release. ## Status Show unmaintained releases | Package | Ubuntu Release | Status | | --- | --- | --- | | mediawiki | 17.04 zesty | Not affected | | 16.10 yakkety | Not affected | | 16.04 LTS xenial | Not in release | | 15.10 wily | Not affected | | 15.04 vivid | Not affected | | 14.10 utopic | Not affected | | 14.04 LTS trusty | Not in release | | 13.10 saucy | Not affected | | 13.04 raring | Not affected | | 12.10 quantal | Not affected | | 12.04 LTS precise | Ignored end of life | | 11.10 oneiric | Ignored end of life | | 11.04 natty | Ignored end of life | | 10.10 maverick | Ignored end of life | | 10.04 LTS lucid | Ignored end of life | | 8.04 LTS hardy | Ignored end of life | --- * [How can I get the fixes?](https://ubuntu.com/security/cves/about#security) * [What do statuses mean?](https://ubuntu.com/security/cves/about#statuses) ## References * [MITRE](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-1581) * [NVD](https://nvd.nist.gov/vuln/detail/CVE-2012-1581) * [Launchpad](https://launchpad.net/bugs/cve/CVE-2012-1581) * [Debian](https://security-tracker.debian.org/tracker/CVE-2012-1581) ### Other references * *
