Description Vincent Danen 2013-02-06 16:47:06 UTC

In addition to the fix for CVE-2013-0169, PolarSSL 1.2.5 corrects the following problem:

"PolarSSL ... The code does not sanity check padlen before running
the padding check, meaning that out-of-bounds comparisons may be
made" (a possible denial-of-service issue for some applications)
