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.
