Opera Software released today the version 7.52 of Opera browser with added security (Linux, FreeBSD, Solaris, Mac OS X and MS-Windows):
- Fixed a URI obfuscation weakness enabling impersonation of legitimate web sites. Illegal characters in addresses will be stripped. This addresses Security Focus Bugtraq ID #10517.
- Solved frame injection vulnerability that allowed for spoofing (Secunia Advisory SA11978).
- Solved certificate verification problem.
Of course there are others improvments not related with security issues which can be viewed in the respectives changelogs, here.
