--- title: "CVE-2009-0269\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-2009-0269?format=md keywords: index, follow --- # CVE-2009-0269 Publication date 26 January 2009 Last updated 24 July 2024 --- Ubuntu priority **Low** [Why this priority?](https://ubuntu.com/security/cves/about#priority ) Toggle side navigation ## Description fs/ecryptfs/inode.c in the eCryptfs subsystem in the Linux kernel before 2.6.28.1 allows local users to cause a denial of service (fault or memory corruption), or possibly have unspecified other impact, via a readlink call that results in an error, leading to use of a -1 return value as an array index. ### From the Ubuntu Security Team The eCryptfs filesystem did not correctly handle certain VFS return codes. A local attacker with write-access to an eCryptfs filesystem could cause a system crash, leading to a denial of service. ## Status Show unmaintained releases | Package | Ubuntu Release | Status | | --- | --- | --- | | linux | 8.10 intrepid | Fixed 2.6.27-11.31 | | 8.04 LTS hardy | Fixed 2.6.24-23.52 | | 7.10 gutsy | Not in release | | 6.06 LTS dapper | Not in release | | linux-source-2.6.15 | 8.10 intrepid | Not in release | | 8.04 LTS hardy | Not in release | | 7.10 gutsy | Not in release | | 6.06 LTS dapper | Not affected | | linux-source-2.6.22 | 8.10 intrepid | Not in release | | 8.04 LTS hardy | Not in release | | 7.10 gutsy | Fixed 2.6.22-16.62 | | 6.06 LTS dapper | Not in release | --- * [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-2009-0269) * [NVD](https://nvd.nist.gov/vuln/detail/CVE-2009-0269) * [Launchpad](https://launchpad.net/bugs/cve/CVE-2009-0269) * [Debian](https://security-tracker.debian.org/tracker/CVE-2009-0269) ### Related Ubuntu Security Notices (USN) + [USN-751-1](https://usn.ubuntu.com/USN-751-1) + Linux kernel vulnerabilities + 6 April 2009 ### Other references *
