Created file-roller tracking bugs for this issue: Affects: fedora-all [bug 1824990] Created file-roller tracking bugs for this issue: Affects: fedora-all [bug 1824990] There's an issue with file-roller, during archive extraction the function extract_archive_thread() doesn't check whether a existing symlink expands to outside extracting path. This weakness can be leveraged by an attacker crafting a malicious archive file containing a determined symbolic link structure, allowing files outside the extraction directory to be overwritten. A well succeeded attack depends on User Interaction by opening and extracting the malicious archive file. The attack has a Low Integrity impact as file creation and overwritten is restricted only to the paths user has permissions to write. It may be a Low Availability impact depending on which files are overwritten. This bug is now closed. Further updates for individual products will be reflected on the CVE page(s): https://access.redhat.com/security/cve/cve-2020-11736 This issue has been addressed in the following products: Red Hat Enterprise Linux 8 Via RHSA-2020:4820 https://access.redhat.com/errata/RHSA-2020:4820 |
