| Vector | AV:N/AC:L/Au:N/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
Python versions through 3.8.3
Description
The issue is related to the
proc pax function in Lib/tarfile.py, which lacks proper header validation, allowing an attacker to craft a TAR archive that can cause an infinite loop when opened by tarfile.open. This can lead to a denial of service. The estimated number of potentially affected devices is not specified.Recommendations
For versions through 3.8.3, consider disabling the
tarfile.open function until a patch is available, or restrict the use of TAR archives to minimize the risk of exploitation.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.DoS
