CVE-2017-11423 openSUSE Leap 42.3:clamav-0.99.3-20.1 moderate 1.7 AV:L/AC:L/Au:S/C:N/I:N/A:P Please Install the update. https://lists.opensuse.org/opensuse-security-announce/2018-01/msg00078.html https://www.suse.com/security/cve/CVE-2017-11423.html CVE-2017-11423 https://bugzilla.suse.com/1049423 SUSE Bug 1049423 https://bugzilla.suse.com/1083915 SUSE Bug 1083915 The 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-2017-12374 openSUSE Leap 42.3:clamav-0.99.3-20.1 important Please Install the update. https://lists.opensuse.org/opensuse-security-announce/2018-01/msg00078.html https://www.suse.com/security/cve/CVE-2017-12374.html CVE-2017-12374 https://bugzilla.suse.com/1077732 SUSE Bug 1077732 The 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-2017-12375 openSUSE Leap 42.3:clamav-0.99.3-20.1 important Please Install the update. https://lists.opensuse.org/opensuse-security-announce/2018-01/msg00078.html https://www.suse.com/security/cve/CVE-2017-12375.html CVE-2017-12375 https://bugzilla.suse.com/1077732 SUSE Bug 1077732 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-2017-12376 openSUSE Leap 42.3:clamav-0.99.3-20.1 important Please Install the update. https://lists.opensuse.org/opensuse-security-announce/2018-01/msg00078.html https://www.suse.com/security/cve/CVE-2017-12376.html CVE-2017-12376 https://bugzilla.suse.com/1077732 SUSE Bug 1077732 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-2017-12377 openSUSE Leap 42.3:clamav-0.99.3-20.1 important Please Install the update. https://lists.opensuse.org/opensuse-security-announce/2018-01/msg00078.html https://www.suse.com/security/cve/CVE-2017-12377.html CVE-2017-12377 https://bugzilla.suse.com/1077732 SUSE Bug 1077732 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-2017-12378 openSUSE Leap 42.3:clamav-0.99.3-20.1 important Please Install the update. https://lists.opensuse.org/opensuse-security-announce/2018-01/msg00078.html https://www.suse.com/security/cve/CVE-2017-12378.html CVE-2017-12378 https://bugzilla.suse.com/1077732 SUSE Bug 1077732 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-2017-12379 openSUSE Leap 42.3:clamav-0.99.3-20.1 important Please Install the update. https://lists.opensuse.org/opensuse-security-announce/2018-01/msg00078.html https://www.suse.com/security/cve/CVE-2017-12379.html CVE-2017-12379 https://bugzilla.suse.com/1077732 SUSE Bug 1077732 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. CVE-2017-12380 openSUSE Leap 42.3:clamav-0.99.3-20.1 important Please Install the update. https://lists.opensuse.org/opensuse-security-announce/2018-01/msg00078.html https://www.suse.com/security/cve/CVE-2017-12380.html CVE-2017-12380 https://bugzilla.suse.com/1077732 SUSE Bug 1077732 libclamav/message.c in ClamAV 0.99.2 allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted e-mail message.
