CVE-2019-12402
Public on
Last Modified:
Description
A resource consumption vulnerability was discovered in apache-commons-compress in the way NioZipEncoding encodes filenames. Applications that use Compress to create archives, with one of the filenames within the archive being controlled by the user, may be vulnerable to this flaw. A remote attacker could exploit this flaw to cause an infinite loop during the archive creation, thus leading to a denial of service.
Statement
This issue does not affect the versions of apache-commons-compress as shipped with Red Hat Enterprise Linux 7, and the versions of rh-java-common-apache-commons-compress and rh-maven35-apache-commons-compress as shipped with Red Hat Software Collections 3, as they used a fallback zip encoding implementation (leveraging java.io) to encode filenames. This issue does not affect the versions of rh-maven36-apache-commons-compress as shipped with Red Hat Software Collection 3 as they already include the patch.

Common Vulnerability Scoring System (CVSS) Score Details
Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
| Red Hat | NVD | |
|---|---|---|
CVSS v3 Base Score | 7.5 | 7.5 |
Attack Vector | Network | Network |
Attack Complexity | Low | Low |
Privileges Required | None | None |
User Interaction | None | None |
Scope | Unchanged | Unchanged |
Confidentiality Impact | None | None |
Integrity Impact | None | None |
Availability Impact | High | High |
CVSS v3 Vector
Red Hat: CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
NVD: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Understanding the Weakness (CWE)
Integrity
Technical Impact: Unexpected State
Availability
Technical Impact: DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory); DoS: Amplification
An infinite loop will cause unexpected consumption of resources, such as CPU cycles or memory. The software's operation may slow down, or cause a long time to respond.
