Precisely the versions as stated in https://openssl.org/news/secadv_20150709.txt are affected:

	This issue affects OpenSSL versions 1.0.2c, 1.0.2b, 1.0.1n and 1.0.1o.

	OpenSSL 1.0.2b/1.0.2c users should upgrade to 1.0.2d
	OpenSSL 1.0.1n/1.0.1o users should upgrade to 1.0.1p

	This issue was reported to OpenSSL on 24th June 2015 by Adam Langley/David
	Benjamin (Google/BoringSSL). The fix was developed by the BoringSSL project.

In other words, the bug was introduced in 1.0.1n resp. 1.0.2b, which was roughly a month before it was fixed again.
