CVE-2010-4256
Publication date 25 January 2011
Last updated 24 July 2024
Ubuntu priority
The pipe_fcntl function in fs/pipe.c in the Linux kernel before 2.6.37 does not properly determine whether a file is a named pipe, which allows local users to cause a denial of service via an F_SETPIPE_SZ fcntl call.
From the Ubuntu Security Team
It was discovered that named pipes did not correctly handle certain fcntl calls. A local attacker could exploit this to crash the system, leading to a denial of service.
