GHSA-VXP5-584Q-C479 Incus has arbitrary file read+write on host via templates/ symlink in malicious image

Summary A specially crafted image or instance backup can be used to read or create/write arbitrary files on the host; possibly leading to arbitrary command execution. Details For container images, internal/server/storage/utils.go calls archive.UnpackimageFile, destPath, .... The tar extraction pa...

External Control of File Name or Path

Overview Affected versions of this package are vulnerable to External Control of File Name or Path via a crafted symlink in the templates directory during image import or instance backup restoration processes. An attacker can access and modify arbitrary files on the host system, potentially leadi...

GHSA-JMR9-QJV8-65GV extract-zip unvalidated symlink path traversal

extract-zip does not validate symlink targets when extracting zip archives. When processing a malicious zip file containing a symlink with a relative path like '../../../../etc/passwd', extract-zip will extract the symlink without validation, allowing it to point outside the extraction directory...

GHSA-73HR-M85F-64V9 Incus has an arbitrary file write on host via `exec-output` symlink in crafted image

Summary The record-output parameter of the /instances/$name/exec endpoint stores the output of the command in the exec-output directory of the instance. If exec-output is a symlink, file named execUUID.stdout and execUUID.stderr can be written to an arbitrary location where the .stdout file will...

External Control of File Name or Path

Overview Affected versions of this package are vulnerable to External Control of File Name or Path through the rootfs symlink during image extraction. An attacker can gain unauthorized access to sensitive files and perform arbitrary file creation or modification on the host by importing a special...

GHSA-2Q3F-Q5PQ-G8WV Incus has an arbitrary file read+write on host via rootfs/ symlink in malicious image

Summary A specially crafted image can be used to read or create/write arbitrary files on the host; possibly leading to arbitrary command execution. Details Incus validates an image as soon as it sees a normal metadata.yaml and a rootfs/ entry, but full extraction can later process a duplicate...
