Debian Security Advisory
DLA-1122-1 asterisk -- LTS security update
- Date Reported:
- 05 Oct 2017
- Affected Packages:
- Security database references:
- In the Debian bugtracking system: Bug 873908.
In Mitre's CVE dictionary: CVE-2017-14100.
- More information:
A security vulnerability was discovered in Asterisk, an Open Source PBX and telephony toolkit, that may lead to unauthorized command execution.
The app_minivm module has an
externnotifyprogram configuration option that is executed by the MinivmNotify dialplan application. The application uses the caller-id name and number as part of a built string passed to the OS shell for interpretation and execution. Since the caller-id name and number can come from an untrusted source, a crafted caller-id name or number allows an arbitrary shell command injection.
For Debian 7
Wheezy, these problems have been fixed in version 1:22.214.171.124~dfsg1-3+deb7u7.
We recommend that you upgrade your asterisk packages.
