Arch Linux Security Advisory ASA-201803-14
==========================================

Severity: Critical
Date : 2018-03-18
CVE-ID : CVE-2012-6706 CVE-2017-6419 CVE-2017-11423 CVE-2018-0202
CVE-2018-1000085
Package : clamav
Type : multiple issues
Remote : Yes
Link : https://security.archlinux.org/AVG-602

Summary
=======

The package clamav before version 0.99.4-1 is vulnerable to multiple
issues including arbitrary code execution and denial of service.

Resolution
==========

Upgrade to 0.99.4-1.

# pacman -Syu "clamav>=0.99.4-1"

The problems have been fixed upstream in version 0.99.4.

Workaround
==========

None.

Description
===========

- CVE-2012-6706 (arbitrary code execution)

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-2017-6419 (arbitrary code execution)

mspack/lzxd.c in libmspack 0.5alpha, as used in ClamAV before 0.99.4,
allows remote attackers to cause a denial of service (heap-based buffer
overflow and application crash) or possibly execute arbitrary code via
a crafted CHM file.

- CVE-2017-11423 (denial of service)

The cabd_read_string function in mspack/cabd.c in libmspack 0.5alpha,
as used in ClamAV before 0.99.4 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-2018-0202 (arbitrary code execution)

A heap overflow has been discovered in ClamAv before 0.99.4 in
pdf_parse_string possibly leading to arbitrary code execution by
inspecting a specially crafted PDF file.

- CVE-2018-1000085 (denial of service)

A heap-based out-of-bounds read has been found in the xar_hash_check
function of the xar decoder of ClamAV before 0.99.4, leading to a
denial of service.

Impact
======

A remote attacker can cause a denial of service or execute arbitrary
code on the affected host by submitting a crafted file for inspection
by ClamAV.

ASA-201803-15: curl: multiple issues

Arch Linux Security Advisory ASA-201803-15
==========================================

Severity: Medium
Date : 2018-03-19
CVE-ID : CVE-2018-1000120 CVE-2018-1000121 CVE-2018-1000122
Package : curl
Type : multiple issues
Remote : Yes
Link : https://security.archlinux.org/AVG-653

Summary
=======

The package curl before version 7.59.0-1 is vulnerable to multiple
issues including denial of service and information disclosure.

Resolution
==========

Upgrade to 7.59.0-1.

# pacman -Syu "curl>=7.59.0-1"

The problems have been fixed upstream in version 7.59.0.

Workaround
==========

None.

Description
===========

- CVE-2018-1000120 (denial of service)

It was found that libcurl did not safely parse FTP URLs when using the
CURLOPT_FTP_FILEMETHOD method. An attacker, able to provide a specially
crafted FTP URL to an application using libcurl, could write a NULL
byte at an arbitrary location, resulting in a crash, or an unspecified
behavior.

- CVE-2018-1000121 (denial of service)

A NULL pointer dereference exists in the LDAP code of curl >= 7.21.0
and < curl 7.59.0, allowing an attacker to cause a denial of service.
libcurl-using applications that allow LDAP URLs, or that allow
redirects to LDAP URLs could be made to crash by a malicious server.

- CVE-2018-1000122 (information disclosure)

A buffer over-read exists in curl >= 7.20.0 and < 7.59.0 in the
RTSP+RTP handling code that allows an attacker to cause a denial of
service or information leakage. When asked to transfer an RTSP URL,
curl could calculate a wrong data length to copy from the read buffer.
The memcpy call would copy data from the heap following the buffer to a
storage area that would subsequently be delivered to the application
(if it didn't cause a crash). This could lead to information leakage or
a denial of service for the application if the server offering the RTSP
data can trigger this.

Impact
======

A remote attacker is able to crash the application or disclose
sensitive information on the affected host.
