--- title: "CVE-2010-2240\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-2010-2240?format=md keywords: index, follow --- # CVE-2010-2240 Publication date 17 August 2010 Last updated 24 July 2024 --- Ubuntu priority **Medium** [Why this priority?](https://ubuntu.com/security/cves/about#priority ) Toggle side navigation ## Description The do\_anonymous\_page function in mm/memory.c in the Linux kernel before 2.6.27.52, 2.6.32.x before 2.6.32.19, 2.6.34.x before 2.6.34.4, and 2.6.35.x before 2.6.35.2 does not properly separate the stack and the heap, which allows context-dependent attackers to execute arbitrary code by writing to the bottom page of a shared memory segment, as demonstrated by a memory-exhaustion attack against the X.Org X server. ### From the Ubuntu Security Team Gael Delalleu, Rafal Wojtczuk, and Brad Spengler discovered that the memory manager did not properly handle when applications grow stacks into adjacent memory regions. A local attacker could exploit this to gain control of certain applications, potentially leading to privilege escalation, as demonstrated in attacks against the X server.
