Description

This security bulletin contains information about 1 vulnerability.


1) Uncaught Exception (CVE-ID: N/A)

CWE-ID: CWE-248 - Uncaught Exception

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to an uncaught exception in the PAX extended header parser when processing attacker-supplied tarballs containing NUL bytes in path or linkpath records. A remote attacker can supply a specially crafted tarball to cause a denial of service.

The exception is triggered after the crafted value reaches filesystem operations and can bypass the consumer's await/try-catch error handling boundary.
