========================================================================== Ubuntu Security Notice USN-2549-1 March 25, 2015
libarchive vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.10 - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS
Summary:
libarchive could be made to crash or overwrite files.
Software Description: - libarchive: Library to read/write archive files
Details:
It was discovered that the libarchive bsdcpio utility extracted absolute paths by default without using the --insecure flag, contrary to expectations. If a user or automated system were tricked into extracting cpio archives containing absolute paths, a remote attacker may be able to write to arbitrary files. (CVE-2015-2304)
Fabian Yamaguchi discovered that libarchive incorrectly handled certain type conversions. A remote attacker could possibly use this issue to cause libarchive to crash, resulting in a denial of service. This issue only affected Ubuntu 12.04 LTS. (CVE-2013-0211)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 14.10: bsdcpio 3.1.2-9ubuntu0.1 libarchive13 3.1.2-9ubuntu0.1
Ubuntu 14.04 LTS: bsdcpio 3.1.2-7ubuntu2.1 libarchive13 3.1.2-7ubuntu2.1
Ubuntu 12.04 LTS: bsdcpio 3.0.3-6ubuntu1.1 libarchive12 3.0.3-6ubuntu1.1
In general, a standard system update will make all the necessary changes.
