Description Adam Mariš 2015-09-07 14:38:21 UTC 
The DateTimeZone constructors are not binary safe. They're parsing the timezone as string, but discard the length when calling timezone_initialize().

Comment 1 Remi Collet 2015-09-07 14:48:55 UTC 
As state in 70277, this bug is not considered by upstream as a security issue, and have not be fixed in 5.4 / 5.5 (security only branches)

Even if trailing char are present (this usually should be not validated user input), there is no risk.
