DESCRIPTION:
A vulnerability has been reported in HAProxy, which can be exploited
by malicious people to potentially compromise a vulnerable system.
The vulnerability is caused due a boundary error when copying data
into the trash buffer and can be exploited to cause a buffer
overflow.
Successful exploitation may allow execution of arbitrary code, but
requires that the global.tune.bufsize configuration option is set to
a value greater than the default and that header rewriting is
configured e.g. via the reqrep or rsprep directives.
The vulnerability is reported in version 1.4.20. Prior versions may
also be affected.
SOLUTION:
Update to version 1.4.21.
PROVIDED AND/OR DISCOVERED BY:
Reported by the vendor.
