Description Joe Orton 2006-09-18 10:37:32 UTC 
+++ This bug was initially created as a clone of Bug #204993 +++

(Description from MITRE)
Multiple heap-based buffer overflows in the (1) str_repeat and (2)
wordwrap functions in ext/standard/string.c in PHP before 5.1.5, when
used on a 64-bit system, have unspecified impact and attack vectors, a
different vulnerability than CVE-2006-1990.

This is the result of using int = size_t * sizt_t where int is 32 bits
and size_t is 64 bits.  The odds of exploiting this remotely are slim
as you would probably have to send 2 gigs of data to a broken app.
