USN-5488-1: OpenSSL vulnerability
21 June 2022
OpenSSL could be made to crash or run programs when the c_rehash script is used.
Releases
Packages
- openssl - Secure Socket Layer (SSL) cryptographic library and tools
- openssl1.0 - Secure Socket Layer (SSL) cryptographic library and tools
Details
Chancen and Daniel Fiala discovered that OpenSSL incorrectly handled the
c_rehash script. A local attacker could possibly use this issue to execute
arbitrary commands when c_rehash is run.
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 22.04
Ubuntu 21.10
Ubuntu 20.04
Ubuntu 18.04
In general, a standard system update will make all the necessary changes.
