Package : lighttpd
Version : 1.4.45-1+deb9u1
CVE ID : CVE-2018-19052
One issue has been discovered in lighttpd: fast webserver with minimal memory
footprint.
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.
