DESCRIPTION:
A vulnerability has been reported in grep, which can be exploited by
malicious people to potentially compromise a user's system.
The vulnerability is caused due to an integer overflow error when
parsing very long lines and can be exploited to cause a heap-based
buffer overflow.
Successful exploitation may allow execution of arbitrary code, but
requires tricking a user into processing a malicious file.
The vulnerability is reported in versions prior to 2.11.
SOLUTION:
Update to version 2.11 or later.
