HAProxy - Load balancer

In pat_match_str() and pat_math_beg() functions, a trailing zero is systematically added at the end of the string, even if the buffer is not large enough to accommodate it. It is a possible buffer overflow. For instance, when the alpn is matched against a list of strings, the sample fetch is filled with a non-null terminated string returned by the SSL library. No trailing zero must be added at the end of this string, because it is outside the buffer. So, to fix the bug, a trailing zero is added only if the buffer is large enough to accommodate it. Otherwise, the sample fetch is duplicated. smp_dup() function adds a trailing zero to the duplicated string, truncating it if it is too long. This patch should fix the issue #718. It must be backported to all supported versions. |
