CVE-2018-19052: an issue was discovered in mod_alias_physical_handler in mod_alias.c in lighttpd before 1.4.50. There is potential ../ path traversal of a single directory above an alias target, with a specific mod_alias configuration where the matched alias lacks a trailing '/' character, but the alias target filesystem path does have a trailing '/' character.
For Debian 9 stretch, this problem has been fixed in version 1.4.45-1+deb9u1.
We recommend that you upgrade your lighttpd packages.
For the detailed security status of lighttpd please refer to its security tracker page at: [link moved to references]
Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: [link moved to references]");
