Security researcher Jason A. Donenfeld has found a vulnerability in a popular WordPress plugin W3 Total Cache that makes sites to obtain sensitive data from an affected site.

Two important holes:

1.Directory listings were enabled on the cache directory, which means anyone could easily recursively download all the database cache keys, and extract ones containing sensitive information, such as password hashes.

2.Even with directory listings off, cache files are by default publicly downloadable, and the key values / file names of the database cache items are easily predictable.

Google is celebrating Srinivasa Ramanujan’s 125th birthday with a new google doodle on its homepage.

Srinivasa Ramanujan FRS (22 December 1887 – 26 April 1920) was an Indian mathematician and autodidact who, with almost no formal training in pure mathematics, made extraordinary contributions to mathematical analysis, number theory, infinite series, and continued fractions. Living in India with no access to the larger mathematical community, which was centered in Europe at the time, Ramanujan developed his own mathematical research in isolation. As a result, he sometimes rediscovered known theorems in addition to producing new work. Ramanujan
was said to be a natural genius by the English mathematician G.H. Hardy, in the same league as mathematicians like Euler and Gauss.
