PDF parser bugs

The following other changes were made: Disable YARA support for licensing reasons (bsc#1101654).

Add HTTPS support for clamsubmit

Fix for DNS resolution for users on IPv4-only machines where IPv6 is not available or is link-local only

Some vulnerabilities have been found in ClamAV, an open source antivirus engine :

CVE-2018-0202

It was found that ClamAV didn't process certain PDF files correctly, relating to a heap overflow. Specially crafted PDFs could yield ClamAV to crash, resulting in a denial of service or potentially execution of arbitrary code.

CVE-2018-1000085

Hanno B&ouml;ck discovered that ClamAV didn't process XAR files correctly. Malformed XAR files could cause ClamAV to crash by an out of bounds heap read. This could result in a denial of service.

For Debian 7 'Wheezy', these problems have been fixed in version 0.99.4+dfsg-1+deb7u1.

We recommend that you upgrade your clamav packages.

Update to 0.99.4

0.99.4 addresses a few outstanding vulnerability bugs. It includes fixes for :

  - CVE-2012-6706

  - CVE-2017-6419

  - CVE-2017-11423 

  - CVE-2018-1000085 

There are also a few bug fixes that were not assigned CVE&rsquo;s, but were important enough to address while we had the chance. One of these was the notorious file descriptor exhaustion bug that caused outages late last January.

In addition to the above, 0.99.4 fixes :

  - CVE-2018-0202: Two newly reported vulnerabilities in the     PDF parsing code.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.

The remote host is affected by the vulnerability described in GLSA-201804-16 (ClamAV: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in ClamAV. Please review       the CVE identifiers referenced below for details.
  Impact :

    A remote attacker, through multiple vectors, could execute arbitrary       code, cause a Denial of Service condition, or have other unspecified       impacts.
  Workaround :

    There is no known workaround at this time.

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3592-1 advisory.

    It was discovered that ClamAV incorrectly handled parsing certain PDF files. A remote attacker could use     this issue to cause ClamAV to crash, resulting in a denial of service, or possibly execute arbitrary code.
    (CVE-2018-0202)

    Hanno Bck discovered that ClamAV incorrectly handled parsing certain XAR files. A remote attacker could     use this issue to cause ClamAV to crash, resulting in a denial of service. (CVE-2018-1000085)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Heap-based buffer overflow in mspack/lzxd.c

mspack/lzxd.c in libmspack 0.5alpha, as used in ClamAV 0.99.2, allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted CHM file. (CVE-2017-6419)

Out-of-bounds access in the PDF parser (CVE-2018-0202)

A VMSF_DELTA memory corruption was discovered in unrar before 5.5.5, as used in Sophos Anti-Virus Threat Detection Engine before 3.37.2 and other products, that can lead to arbitrary code execution. An integer overflow can be caused in DataSize+CurChannel. The result is a negative value of the 'DestPos' variable, which allows the attacker to write out of bounds when setting Mem[DestPos]. (CVE-2012-6706)

ClamAV version version 0.99.3 contains a Out of bounds heap memory read vulnerability in XAR parser, function xar_hash_check() that can result in Leaking of memory, may help in developing exploit chains..
This attack appear to be exploitable via The victim must scan a crafted XAR file. (CVE-2018-1000085)

Stack-based buffer over-read in cabd_read_string function

The cabd_read_string function in mspack/cabd.c in libmspack 0.5alpha, as used in ClamAV 0.99.2 and other products, allows remote attackers to cause a denial of service (stack-based buffer over-read and application crash) via a crafted CAB file. (CVE-2017-11423)

This update for clamav fixes the following issues :
