CVE-2008-3276: Integer Overflow
First published: Fri Aug 15 2008(Updated: )
Description of problem: Eugene Teo reported that an integer overflow flaw was found in the Linux kernel dccp_setsockopt_change() function. The vulnerability exists due to a lack of sanitisation performed on a user-controlled integer value before the value is employed as the size argument of a memory allocation operation. An attacker may leverage this vulnerability to trigger a kernel panic on a victim's machine remotely.
