Synopsis

The remote Apple TV device is affected by multiple vulnerabilities

Description

According to its banner, the version of Apple TV on the remote device is prior to 14.3. It is, therefore, affected by multiple vulnerabilities as described in the HT212005 advisory:

- An out-of-bounds write issue within CoreAudio processing may allow a maliciously crafted audio file to cause arbitrary code execution. (CVE-2020-27948)

- A memory corruption issue within FontParser processing may allow a maliciously crafted font file to cause arbitrary code execution. (CVE-2020-27943, CVE-2020-27944, CVE-2020-29624)

- An out-of-bounds read isue within ImageIO processing may allow maliciously crafted image to cause arbitrary code execution. (CVE-2020-29618) Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Apple TV version 14.3 or later.
