- ------------------------------------------------------------------------- Debian LTS Advisory DLA-3770-1 [email protected] https://www.debian.org/lts/security/ Thorsten Alteholz March 23, 2024 https://wiki.debian.org/LTS
- -------------------------------------------------------------------------

Package : libnet-cidr-lite-perl Version : 0.21-2+debu10u1 CVE ID : CVE-2021-47154

An issue has been found in libnet-cidr-lite-perl, a module for merging IPv4 or IPv6 CIDR address ranges.

Extraneous zero characters at the beginning of an IP address string might allow attackers to bypass access control that is based on IP addresses.

Please check your application whether it accidentally allows such leading zero characters (that are normally meant to indicate octal numbers).

For Debian 10 buster, this problem has been fixed in version 0.21-2+debu10u1.

We recommend that you upgrade your libnet-cidr-lite-perl packages.

For the detailed security status of libnet-cidr-lite-perl please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/libnet-cidr-lite-perl

Solution

Upgrade the libnet-cidr-lite-perl packages.
