[Pkg-sysvinit-devel] Bug#431224: update-rc.d: package names with + or * not installable

[Steffen Moeller]

Package: sysv-rc
Version: 2.86.ds1-38
Severity: important
Tags: patch

dpkg calls update-rc.d to execute the post-inst script. In line 110, the
name of the package becomes part of a regular expression. The occurrence
of + or other characters with a special meaning that may be part of the
package name lets the script bail out:

Nested quantifiers in regex; marked by <-- HERE in m/^[SK]\d\dfact++ <--
HERE $/ at /usr/sbin/update-rc.d line 110.

The patch below takes extra precaution to escape the most likely
candidates: * and +.

Best regards

Steffen
