Symantec Web Gateway Anti-Virus Definition < 20160628.037 Multiple Vulnerabilities (SYM16-010) (credentialed check)

Critical Nessus Plugin ID 92001

Synopsis

A web security application hosted on the remote web server is affected by multiple vulnerabilities.

Description

According to its self-reported anti-virus definition version number, the remote web server is hosting a version of Symantec Web Gateway with an anti-virus definition version prior to 20160628.037. 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 the Symantec Web Gateway Anti-Virus definitions to version 20160628.037 or later.
