  script_tag(name:"insight", value:"A specific flaw within the processing of recovery volumes exists in UnRAR, an unarchiver for rar files. It allows remote attackers to execute arbitrary code on affected installations. User interaction is required to exploit this vulnerability. The target must visit a malicious page or open a malicious rar file.

For Debian 10 buster, this problem has been fixed in version 1:5.6.6-1+deb10u4.

We recommend that you upgrade your unrar-nonfree packages.

For the detailed security status of unrar-nonfree please refer to its security tracker page at: [link moved to references]
