    descriptionClamAV 0.99.3 ============= This release is a security release and is recommended for all ClamAV users. Please see details below : 1. ClamAV UAF (use-after-free) Vulnerabilities (CVE-2017-12374) --------------------------------------------------------------- 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. 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. - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H - https://bugzilla.clamav.net/show_bug.cgi?id=11939 2. ClamAV Buffer Overflow Vulnerability (CVE-2017-12375) -------------------------------------------------------- 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. 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. - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N /A:L - https://bugzilla.clamav.net/show_bug.cgi?id=11940 3. ClamAV Buffer Overflow in handle_pdfname Vulnerability (CVE-2017-12376) ---------------------------------------------------------------------- ---- 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 buffer overflow when ClamAV scans the malicious file, allowing the attacker to cause a DoS condition or potentially execute arbitrary code. - https://bugzilla.clamav.net/show_bug.cgi?id=11942 - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H 4. ClamAV Mew Packet Heap Overflow Vulnerability (CVE-2017-12377) ----------------------------------------------------------------- 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 overflow condition when ClamAV scans the malicious file, allowing the attacker to cause a DoS condition or potentially execute arbitrary code on the affected device. - https://bugzilla.clamav.net/show_bug.cgi?id=11943 - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L /A:L 5. ClamAV Buffer Over Read Vulnerability (CVE-2017-12378) --------------------------------------------------------- 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 buffer over-read condition when ClamAV scans the malicious .tar file, potentially allowing the attacker to cause a DoS condition on the affected device. - https://bugzilla.clamav.net/show_bug.cgi?id=11946 - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N /A:L 6. ClamAV Buffer Overflow in messageAddArgument Vulnerability (CVE-2017-12379) ---------------------------------------------------------------------- -------- 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 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. - https://bugzilla.clamav.net/show_bug.cgi?id=11944 - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L /A:L 7. ClamAV Null Dereference Vulnerability (CVE-2017-12380) --------------------------------------------------------- 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 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. - https://bugzilla.clamav.net/show_bug.cgi?id=11945 - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H Further fixes/changes --------------------- Also included are 2 minor fixes to properly detect openssl install locations on FreeBSD 11, and prevent false warnings about zlib 1.2.1# version numbers. Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

An unauthenticated, remote attacker could exploit this vulnerability by sending a crafted .pdf file to an affected device. This action could cause a buffer overflow when ClamAV scans the malicious file, allowing the attacker to cause a DoS condition or potentially execute arbitrary code. - https://bugzilla.clamav.net/show_bug.cgi?id=11942 - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H 4. ClamAV Mew Packet Heap Overflow Vulnerability (CVE-2017-12377) ----------------------------------------------------------------- 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 overflow condition when ClamAV scans the malicious file, allowing the attacker to cause a DoS condition or potentially execute arbitrary code on the affected device. - https://bugzilla.clamav.net/show_bug.cgi?id=11943 - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L /A:L 5. ClamAV Buffer Over Read Vulnerability (CVE-2017-12378) --------------------------------------------------------- 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 buffer over-read condition when ClamAV scans the malicious .tar file, potentially allowing the attacker to cause a DoS condition on the affected device. - https://bugzilla.clamav.net/show_bug.cgi?id=11946 - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N /A:L 6. ClamAV Buffer Overflow in messageAddArgument Vulnerability (CVE-2017-12379) ---------------------------------------------------------------------- -------- 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 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. - https://bugzilla.clamav.net/show_bug.cgi?id=11944 - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L /A:L 7. ClamAV Null Dereference Vulnerability (CVE-2017-12380) --------------------------------------------------------- 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 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. - https://bugzilla.clamav.net/show_bug.cgi?id=11945 - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H Further fixes/changes --------------------- Also included are 2 minor fixes to properly detect openssl install locations on FreeBSD 11, and prevent false warnings about zlib 1.2.1# version numbers.
