Arch Linux Security Advisory ASA-201802-9
Date : 2018-02-20
CVE-ID : CVE-2017-6419 CVE-2017-11423
Package : libmspack
Type : multiple issues
Remote : Yes
Link : https://security.archlinux.org/AVG-603
The package libmspack before version 1:0.6alpha-1 is vulnerable to
multiple issues including arbitrary code execution and denial of
Upgrade to 1:0.6alpha-1.
# pacman -Syu "libmspack>=1:0.6alpha-1"
The problems have been fixed upstream in version 0.6alpha.
- CVE-2017-6419 (arbitrary code execution)
mspack/lzxd.c in libmspack 0.5alpha, as used in ClamAV before 0.99.3,
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 0.99.3 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.
A remote attacker is able to crash the application or execute arbitrary
code by providing a maliciously-crafted file.
