Jason Buberel reports:

+
A security-related issue has been reported in Go's math/big + package. The issue was introduced in Go 1.5. We recommend that all + users upgrade to Go 1.5.3, which fixes the issue. Go programs must + be recompiled with Go 1.5.3 in order to receive the fix.
+
The Go team would like to thank Nick Craig-Wood for identifying the + issue.
+
This issue can affect RSA computations in crypto/rsa, which is used + by crypto/tls. TLS servers on 32-bit systems could plausibly leak + their RSA private key due to this issue. Other protocol + implementations that create many RSA signatures could also be + impacted in the same way.
+
Specifically, incorrect results in one part of the RSA Chinese + Remainder computation can cause the result to be incorrect in such a + way that it leaks one of the primes. While RSA blinding should + prevent an attacker from crafting specific inputs that trigger the + bug, on 32-bit systems the bug can be expected to occur at random + around one in 2^26 times. Thus collecting around 64 million + signatures (of known data) from an affected server should be enough + to extract the private key used.
+
On 64-bit systems, the frequency of the bug is so low (less than + one in 2^50) that it would be very difficult to exploit. + Nonetheless, everyone is strongly encouraged to upgrade.
