EulerOS 2.0 SP3 : libmspack (EulerOS-SA-2019-2609)

high Nessus Plugin ID 132144

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

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)

- 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)

- 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)

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.

Solution

Update the affected libmspack packages.
