Ubuntu Security Notice USN-3699-1
July 03, 2018
zziplib vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- - Ubuntu 18.04 LTS
- - Ubuntu 17.10
- - Ubuntu 16.04 LTS
- - Ubuntu 14.04 LTS
Summary:
zziplib could be made to crash or run programs as your login if it opened a
specially crafted file.
Software Description:
- - zziplib: library providing read access on ZIP-archives - library
Details:
It was discovered that zziplib incorrectly handled certain malformed ZIP
files. If a user or automated system were tricked into opening a specially
crafted ZIP file, a remote attacker could cause zziplib to crash, resulting
in a denial of service, or possibly execute arbitrary code.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 18.04 LTS:
libzzip-0-13 0.13.62-3.1ubuntu0.18.04.1
Ubuntu 17.10:
libzzip-0-13 0.13.62-3.1ubuntu0.17.10.1
Ubuntu 16.04 LTS:
libzzip-0-13 0.13.62-3ubuntu0.16.04.2
Ubuntu 14.04 LTS:
libzzip-0-13 0.13.62-2ubuntu0.2
In general, a standard system update will make all the necessary changes.
