Several vulnerabilities were discovered in WebKitGTK+.

CVE-2017-5753
Versions affected: WebKitGTK+ before 2.18.5.
Credit to Jann Horn of Google Project Zero; and Paul Kocher in
collaboration with Daniel Genkin of University of Pennsylvania and
University of Maryland, Daniel Gruss of Graz University of
Technology, Werner Haas of Cyberus Technology, Mike Hamburg of
Rambus (Cryptography Research Division), Moritz Lipp of Graz
University of Technology, Stefan Mangard of Graz University of
Technology, Thomas Prescher of Cyberus Technology, Michael Schwarz
of Graz University of Technology, and Yuval Yarom of University of
Adelaide and Data61.
Impact: Systems with microprocessors utilizing speculative execution
and branch prediction may allow unauthorized disclosure of
information to an attacker via a side-channel analysis. This variant
of the Spectre vulnerability triggers the speculative execution by
performing a bounds-check bypass. Description: Security improvements
are included to mitigate the effects.

CVE-2017-5715
Versions affected: WebKitGTK+ before 2.18.5.

University of Technology, Stefan Mangard of Graz University of
Technology, Thomas Prescher of Cyberus Technology, Michael Schwarz
of Graz University of Technology, and Yuval Yarom of University of
Adelaide and Data61.
Impact: Systems with microprocessors utilizing speculative execution
and branch prediction may allow unauthorized disclosure of
information to an attacker via a side-channel analysis. This variant
of the Spectre vulnerability triggers the speculative execution by
utilizing branch target injection. Description: Security
improvements are included to mitigate the effects.


We recommend updating to the last stable version of WebKitGTK+. It is
