Pike is a general purpose programming language, able to be used for multiple tasks.
Some input is not properly sanitised before being used in a SQL statement in the underlying PostgreSQL database.
A remote attacker could provide malicious input to a pike program, which might result in the execution of arbitrary SQL statements.
There is no known workaround at this time.
All pike users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-lang/pike-7.6.86"
