Symantec Endpoint Protection Client 12.1.x < 12.1 RU6 MP5 Multiple Vulnerabilities (SYM16-010)

Critical Nessus Plugin ID 91895

Synopsis

The version of Symantec Endpoint Protection Client installed on the remote host is affected by multiple vulnerabilities.

Description

The version of Symantec Endpoint Protection Client installed on the remote host is 12.1 prior to 12.1 RU6 MP5. It is, therefore, affected by multiple vulnerabilities :

- An array indexing error exists in the UnRAR component in the Unpack::ShortLZ() function in unpack15.cpp that is triggered when decompressing RAR files. An unauthenticated, remote attacker can exploit this, via a specially crafted RAR file, to corrupt memory, resulting in the execution of arbitrary code. (CVE-2016-2207)

- An overflow condition exists when handling PowerPoint documents due to improper validation of user-supplied input when handling a misaligned stream-cache. An unauthenticated, remote attacker can exploit this, via a specially crafted PPT file, to cause a stack-based buffer overflow, resulting in the execution of arbitrary code. (CVE-2016-2209)

- An overflow condition exists in the CSymLHA::get_header() function in Dec2LHA.dll that is triggered when decompressing LZH and LHA archives. An unauthenticated, remote attacker can exploit this, via a specially crafted file, to cause a stack-based buffer overflow, resulting in the execution of arbitrary code.
(CVE-2016-2210)

- Multiple flaws exist in the libmspack library due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit these issues, via a specially crafted file, to crash processes linked against the library or execute arbitrary code.
(CVE-2016-2211)

- An overflow condition exists in the CMIMEParser::UpdateHeader() function due to improper validation of user-supplied input when parsing MIME messages. An unauthenticated, remote attacker can exploit this, via a specially crafted MIME message, to cause a heap-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2016-3644)

- An array indexing error exists in the scan engine decomposer in the LPkOldFormatDecompressor::UnShrink() function that is triggered when decoding ZIP archives.
An unauthenticated, remote attacker can exploit this, via a specially crafted ZIP file, to cause a denial of service condition or the execution of arbitrary code.
(CVE-2016-3645)

- An integer overflow condition exists in the Attachment::setDataFromAttachment() function in Dec2TNEF.dll that is triggered when decoding TNEF files.
An unauthenticated, remote attacker can exploit this, via a specially crafted TNEF file, to cause a denial of service condition or the execution of arbitrary code.
(CVE-2016-3646)

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 Symantec Endpoint Protection Client version 12.1 RU6 MP5 or later.
