--- title: "CVE-2010-4072\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-2010-4072?format=md keywords: index, follow --- # CVE-2010-4072 Publication date 29 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 copy\_shmid\_to\_user function in ipc/shm.c in the Linux kernel before 2.6.37-rc1 does not initialize a certain structure, which allows local users to obtain potentially sensitive information from kernel stack memory via vectors related to the shmctl system call and the "old shm interface." ### From the Ubuntu Security Team Kees Cook and Vasiliy Kulikov discovered that the shm interface did not clear kernel memory correctly. 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 | 10.10 maverick | Fixed 2.6.35-24.42 | | 10.04 LTS lucid | Fixed 2.6.32-27.49 | | 9.10 karmic | Fixed 2.6.31-22.70 | | 9.04 jaunty | Ignored end of life | | 8.04 LTS hardy | Fixed 2.6.24-28.86 | | 6.06 LTS dapper | Not in release | | linux-ec2 | 10.10 maverick | Ignored end of life | | 10.04 LTS lucid | Fixed 2.6.32-311.23 | | 9.10 karmic | Fixed 2.6.31-307.23 | | 9.04 jaunty | Not in release | | 8.04 LTS hardy | Not in release | | 6.06 LTS dapper | Not in release | | linux-fsl-imx51 | 10.10 maverick | Not in release | | 10.04 LTS lucid | Fixed 2.6.31-608.22 | | 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 | 10.10 maverick | Not in release | | 10.04 LTS lucid | Fixed 2.6.35-25.44~lucid1 | | 9.10 karmic | Not in release | | 9.04 jaunty | Not in release | | 8.04 LTS hardy | Not in release | | 6.06 LTS dapper | Not in release | | linux-mvl-dove | 10.10 maverick | Fixed 2.6.32-416.33 | | 10.04 LTS lucid | Fixed 2.6.32-216.33 | | 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 | 10.10 maverick | Not in release | | 10.04 LTS lucid | Not in release | | 9.10 karmic | Not in release | | 9.04 jaunty | Not in release | | 8.04 LTS hardy | Not in release | | 6.06 LTS dapper | Fixed 2.6.15-55.91 | | linux-ti-omap4 | 10.10 maverick | Fixed 2.6.35-903.22 | | 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-2010-4072?format=md#patch-details) ### Patch details For informational purposes only.
