========================================================================== Ubuntu Security Notice USN-3337-1 June 21, 2017
valgrind vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 17.04 - Ubuntu 16.10 - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS
Summary:
Valgrind could be made to crash or run programs if it opened a specially crafted file.
Software Description: - valgrind: instrumentation framework for building dynamic analysis tools
Details:
It was discovered that Valgrind incorrectly handled certain string operations. If a user or automated system were tricked into processing a specially crafted binary, a remote attacker could possibly execute arbitrary code. This issue only affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS and Ubuntu 16.10. (CVE-2016-2226)
It was discovered that Valgrind incorrectly handled parsing certain binaries. If a user or automated system were tricked into processing a specially crafted binary, a remote attacker could use this issue to cause Valgrind to crash, resulting in a denial of service. (CVE-2016-4487, CVE-2016-4488, CVE-2016-4489, CVE-2016-4490, CVE-2016-4491, CVE-2016-4492, CVE-2016-4493, CVE-2016-6131)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 17.04: valgrind 1:3.12.0-1ubuntu1.1
Ubuntu 16.10: valgrind 1:3.12.0~svn20160714-1ubuntu2.1
Ubuntu 16.04 LTS: valgrind 1:3.11.0-1ubuntu4.2
Ubuntu 14.04 LTS: valgrind 1:3.10.1-1ubuntu3~14.5
In general, a standard system update will make all the necessary changes.
