Subject: malloc: Check for integer overflow in memalign.
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9c77803abebe02a99a5329e28627e1ad6d074cfe;p=thirdparty%2Fglibc.git

malloc: Check for integer overflow in memalign.

A large bytes parameter to memalign could cause an integer overflow
and corrupt allocator internals. Check the overflow does not occur
before continuing with the allocation.

ChangeLog:

	[BZ #15857]
	* malloc/malloc.c (__libc_memalign): Check the value of bytes
	does not overflow.
