--- title: "CVE-2010-4082\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-2010-4082?format=md keywords: index, follow --- # CVE-2010-4082 Publication date 30 November 2010 Last updated 24 July 2024 --- Ubuntu priority **Low** [Why this priority?](https://ubuntu.com/security/cves/about#priority ) Toggle side navigation ## Description The viafb\_ioctl\_get\_viafb\_info function in drivers/video/via/ioctl.c in the Linux kernel before 2.6.36-rc5 does not properly initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel stack memory via a VIAFB\_GET\_INFO ioctl call. ### From the Ubuntu Security Team Dan Rosenberg discovered that the VIA video driver did not correctly clear kernel memory. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy. ## Status Show unmaintained releases | Package | Ubuntu Release | Status | | --- | --- | --- | | linux | 11.04 natty | Not affected | | 10.10 maverick | Fixed 2.6.35-23.36 | | 10.04 LTS lucid | Fixed 2.6.32-26.46 | | 9.10 karmic | Fixed 2.6.31-22.73 | | 8.04 LTS hardy | Not affected | | 6.06 LTS dapper | Not in release | | linux-ec2 | 11.04 natty | Not in release | | 10.10 maverick | Ignored end of life | | 10.04 LTS lucid | Fixed 2.6.32-310.19 | | 9.10 karmic | Fixed 2.6.31-307.27 | | 8.04 LTS hardy | Not in release | | 6.06 LTS dapper | Not in release | | linux-fsl-imx51 | 11.04 natty | Not in release | | 10.10 maverick | Not in release | | 10.04 LTS lucid | Fixed 2.6.31-609.26 | | 9.10 karmic | Fixed 2.6.31-112.30 | | 8.04 LTS hardy | Not in release | | 6.06 LTS dapper | Not in release | | linux-lts-backport-maverick | 11.04 natty | Not in release | | 10.10 maverick | Not in release | | 10.04 LTS lucid | Fixed 2.6.35-23.40~lucid1 | | 9.10 karmic | Not in release | | 8.04 LTS hardy | Not in release | | 6.06 LTS dapper | Not in release | | linux-lts-backport-natty | 11.04 natty | Not in release | | 10.10 maverick | Not in release | | 10.04 LTS lucid | Not affected | | 8.04 LTS hardy | Not in release | | linux-mvl-dove | 11.04 natty | Not in release | | 10.10 maverick | Fixed 2.6.32-414.30 | | 10.04 LTS lucid | Fixed 2.6.32-213.29 | | 9.10 karmic | Ignored end of life | | 8.04 LTS hardy | Not in release | | 6.06 LTS dapper | Not in release | | linux-source-2.6.15 | 11.04 natty | Not in release | | 10.10 maverick | Not in release | | 10.04 LTS lucid | Not in release | | 9.10 karmic | Not in release | | 8.04 LTS hardy | Not in release | | 6.06 LTS dapper | Not affected | | linux-ti-omap4 | 11.04 natty | Not affected | | 10.10 maverick | Fixed 2.6.35-903.23 | | 10.04 LTS lucid | Not in release | | 9.10 karmic | Not in release | | 8.04 LTS hardy | Not in release | | 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) * [Patch details](https://ubuntu.com/security/CVE-2010-4082?format=md#patch-details) ### Patch details For informational purposes only.
