[ASA-201802-1] clamav: multiple issues
Arch Linux Security Advisory ASA-201802-1 ========================================= Severity: Critical Date : 2018-02-09 CVE-ID : CVE-2017-6418 CVE-2017-6420 CVE-2017-12374 CVE-2017-12375 CVE-2017-12376 CVE-2017-12377 CVE-2017-12378 CVE-2017-12379 CVE-2017-12380 Package : clamav Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-601 Summary ======= The package clamav before version 0.99.3-1 is vulnerable to multiple issues including arbitrary code execution and denial of service. Resolution ========== Upgrade to 0.99.3-1. # pacman -Syu "clamav>=0.99.3-1" The problems have been fixed upstream in version 0.99.3. Workaround ========== None. Description =========== - CVE-2017-6418 (denial of service) libclamav/message.c in ClamAV before 0.99.3 allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted e-mail message. - CVE-2017-6420 (denial of service) The wwunpack function in libclamav/wwunpack.c in ClamAV before 0.99.3 allows remote attackers to cause a denial of service (use-after-free) via a crafted PE file with WWPack compression. - CVE-2017-12374 (denial of service) ClamAV AntiVirus software versions 0.99.2 and prior contain a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to a lack of input validation checking mechanisms during certain mail parsing operations (mbox.c operations on bounce messages). If successfully exploited, the ClamAV software could allow a variable pointing to the mail body which could cause a used after being free (use-after-free) instance which may lead to a disruption of services on an affected device to include a denial of service condition. - CVE-2017-12375 (denial of service) ClamAV AntiVirus software versions 0.99.2 and prior contain a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to a lack of input validation checking mechanisms during certain mail parsing functions (the rfc2047 function in mbox.c). An unauthenticated, remote attacker could exploit this vulnerability by sending a crafted email to the affected device. This action could cause a buffer overflow condition when ClamAV scans the malicious email, allowing the attacker to potentially cause a DoS condition on an affected device. - CVE-2017-12376 (arbitrary code execution) ClamAV AntiVirus software versions 0.99.2 and prior contain a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition or potentially execute arbitrary code on an affected device. The vulnerability is due to improper input validation checking mechanisms when handling Portable Document Format (.pdf) files sent to an affected device. An unauthenticated, remote attacker could exploit this vulnerability by sending a crafted .pdf file to an affected device. This action could cause a handle_pdfname (in pdf.c) buffer overflow when ClamAV scans the malicious file, allowing the attacker to cause a DoS condition or potentially execute arbitrary code. - CVE-2017-12377 (arbitrary code execution) ClamAV AntiVirus software versions 0.99.2 and prior contain a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition or potentially execute arbitrary code on an affected device. The vulnerability is due to improper input validation checking mechanisms in mew packet files sent to an affected device. A successful exploit could cause a heap-based buffer over-read condition in mew.c when ClamAV scans the malicious file, allowing the attacker to cause a DoS condition or potentially execute arbitrary code on the affected device. - CVE-2017-12378 (denial of service) ClamAV AntiVirus software versions 0.99.2 and prior contain a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper input validation checking mechanisms of .tar (Tape Archive) files sent to an affected device. A successful exploit could cause a checksum buffer over-read condition when ClamAV scans the malicious .tar file, potentially allowing the attacker to cause a DoS condition on the affected device. - CVE-2017-12379 (arbitrary code execution) ClamAV AntiVirus software versions 0.99.2 and prior contain a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition or potentially execute arbitrary code on an affected device. The vulnerability is due to improper input validation checking mechanisms in the message parsing function on an affected system. An unauthenticated, remote attacker could exploit this vulnerability by sending a crafted email to the affected device. This action could cause a messageAddArgument (in message.c) buffer overflow condition when ClamAV scans the malicious email, allowing the attacker to potentially cause a DoS condition or execute arbitrary code on an affected device. - CVE-2017-12380 (denial of service) ClamAV AntiVirus software versions 0.99.2 and prior contain a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper input validation checking mechanisms in mbox.c during certain mail parsing functions of the ClamAV software. An unauthenticated, remote attacker could exploit this vulnerability by sending a crafted email to the affected device. An exploit could trigger a NULL pointer dereference condition when ClamAV scans the malicious email, which may result in a DoS condition. Impact ====== A remote attacker is able to execute arbitrary code or crash the application on the affected host when processing a maliciously crafted file.
