According to the versions of the libmspack package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - chmd_read_headers in mspack/chmd.c in libmspack before     0.8alpha accepts a filename that has '\0' as its first     or second character (such as the '/\0'     name).(CVE-2018-18585)

  - ** DISPUTED ** chmextract.c in the chmextract sample     program, as distributed with libmspack before 0.8alpha,     does not protect against absolute/relative pathnames in     CHM files, leading to Directory Traversal. NOTE: the     vendor disputes that this is a libmspack vulnerability,     because chmextract.c was only intended as a source-code     example, not a supported application.(CVE-2018-18586)

  - The cabd_read_string function in mspack/cabd.c in     libmspack 0.5alpha, as used in ClamAV 0.99.2 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-2017-11423)

  - mspack/lzxd.c in libmspack 0.5alpha, as used in ClamAV     0.99.2, allows remote attackers to cause a denial of     service (heap-based buffer overflow and application     crash) or possibly have unspecified other impact via a     crafted CHM file.(CVE-2017-6419)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

CVE-2017-6419 CVE-2017-11423

Two vulnerabilities have been fixed that can be used for denial of service or maybe unspecified impact via drafted files (heap-based buffer overflow and stack-based buffer over-read causing application crash)

For Debian 7 'Wheezy', these problems have been fixed in version 0.99.2+dfsg-0+deb7u5.

We recommend that you upgrade your clamav packages.

Heap-based buffer overflow in mspack/lzxd.c

mspack/lzxd.c in libmspack 0.5alpha, as used in ClamAV 0.99.2, allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted CHM file. (CVE-2017-6419)

Out-of-bounds access in the PDF parser (CVE-2018-0202)

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-2012-6706)

ClamAV version version 0.99.3 contains a Out of bounds heap memory read vulnerability in XAR parser, function xar_hash_check() that can result in Leaking of memory, may help in developing exploit chains..
This attack appear to be exploitable via The victim must scan a crafted XAR file. (CVE-2018-1000085)

Stack-based buffer over-read in cabd_read_string function

The cabd_read_string function in mspack/cabd.c in libmspack 0.5alpha, as used in ClamAV 0.99.2 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-2017-11423)

This update for clamav fixes the following issues :

Security issues fixed :

  - CVE-2012-6706: VMSF_DELTA filter inside the unrar     implementation allows an arbitrary memory write     (bsc#1045315).

  - CVE-2017-6419: A heap-based buffer overflow that can     lead to a denial of service in libmspack via a crafted     CHM file (bsc#1052449).

  - CVE-2017-11423: A stack-based buffer over-read that can     lead to a denial of service in mspack via a crafted CAB     file (bsc#1049423).

  - CVE-2018-1000085: An out-of-bounds heap read     vulnerability was found in XAR parser that can lead to a     denial of service (bsc#1082858).

  - CVE-2018-0202: Fixed two vulnerabilities in the PDF     parsing code (bsc#1083915).
