Off-by-one error in the WebSocketHandshake::readServerHandshake function in websockets/WebSocketHandshake.cpp in WebCore in WebKit before r56380, as used in Qt and other products, allows remote websockets servers to cause a denial of service (memory corruption) or possibly have unspecified other impact via an upgrade header that is long and invalid.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - WebKit: use-after-free vulnerability in handling of attribute manipulation (CVE-2010-1119)

  - WebKit: off-by-one memory read out of bounds vulnerability in handling of HTML lists (CVE-2010-1773)

  - Use-after-free vulnerability in WebKit in Apple Safari before 5.0 on Mac OS X 10.5 through 10.6 and     Windows, and before 4.1 on Mac OS X 10.4, allows remote attackers to execute arbitrary code or cause a     denial of service (application crash) via vectors related to the contentEditable attribute and removing     container elements. (CVE-2010-1396)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

Various bugs in webkit have been fixed. The CVE id's are :
