The private-browsing implementation in WebKit in Apple Safari before 6.2.8, 7.x before 7.1.8, and 8.x before 8.0.8 does not prevent caching of HTTP authentication credentials, which makes it easier for remote attackers to track users via a crafted web site.

  + Fix the build with GTK+ < 3.16.

  - Build with -DENABLE_DATABASE_PROCESS=OFF and

    -DENABLE_INDEXED_DATABASE=OFF to avoid an issue with GCC     4.8.

Versions of Safari prior to 6.2.8 / 7.1.8 / 8.0.8 are reportedly affected by the following vulnerabilities :

 - An unspecified flaw exists that allows an attacker to spoof UI elements by using crafted web pages. (CVE-2015-3729)
 - Multiple memory corruption flaws exist in WebKit due to improper validation of user-supplied input. An attacker can exploit these, by using a crafted web page, to execute arbitrary code. (CVE-2015-3730, CVE-2015-3731, CVE-2015-3732, CVE-2015-3733, CVE-2015-3734, CVE-2015-3735, CVE-2015-3736, CVE-2015-3737, CVE-2015-3738, CVE-2015-3739, CVE-2015-3740, CVE-2015-3741, CVE-2015-3742, CVE-2015-3743, CVE-2015-3744, CVE-2015-3745, CVE-2015-3746, CVE-2015-3747, CVE-2015-3748, CVE-2015-3749)
 - A security policy bypass vulnerability exists in WebKit related to handling Content Security Policy report requests. An attacker can exploit this to bypass the HTTP Strict Transport Security policy. (CVE-2015-3750)
 - A security policy bypass vulnerability exists in WebKit that allows websites to use video controls to load images nested in object elements in violation of Content Security Policy directives. (CVE-2015-3751)
 - An information disclosure vulnerability exists in WebKit related to how cookies are added to Content Security Policy report requests, which results in cookies being exposed to cross-origin requests. Also, cookies set during regular browsing are sent during private browsing. (CVE-2015-3752)
 - An information disclosure vulnerability exists in the WebKit Canvas component when images are called using URLs that redirect to a data:image resource. An attacker, using a malicious website, can exploit this to disclose image data cross-origin. (CVE-2015-3753)
 - An information disclosure vulnerability exists in WebKit page loading where the caching of HTTP authentication credentials entered in private browsing mode were carried over into regular browsing, resulting in a user's private browsing history being exposed. (CVE-2015-3754)
 - A flaw in the WebKit process model allows a malicious website to display an arbitrary URL, which can allow user interface spoofing. (CVE-2015-3755)

The version of Apple Safari installed on the remote Mac OS X host is prior to 6.2.8 / 7.1.8 / 8.0.8. It is, therefore, affected by the following vulnerabilities :

  - An unspecified flaw exists that allows an attacker to     spoof UI elements by using crafted web pages.
    (CVE-2015-3729)

  - Multiple memory corruption flaws exist in WebKit due     to improper validation of user-supplied input.
