CVE-2014-1912
Public on
Last Modified:
Description
It was discovered that the socket.recvfrom_into() function failed to check the size of the supplied buffer. This could lead to a buffer overflow when the function was called with an insufficiently sized buffer.
Statement
This issue did not affect the versions of python as shipped with Red Hat Enterprise Linux 5 as they did not include the vulnerable socket.recvfrom_into() function. This issue was also corrected in the version of python shipped with Red Hat Enterprise Linux 7.0 prior to release.
The Red Hat Security Response Team has rated this issue as having Moderate security impact. A future update may address this issue in Red Hat Software Collections. For additional information, refer to the Issue Severity Classification: https://access.redhat.com/security/updates/classification/.

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 v2 Base Score | 5.1 | 7.5 |
Attack Vector | Network | Network |
Access Complexity | High | Low |
Authentication | None | None |
Confidentiality Impact | Partial | Partial |
Integrity Impact | Partial | Partial |
Availability Impact | Partial | Partial |
CVSS v2 Vector
Red Hat: AV:N/AC:H/Au:N/C:P/I:P/A:P
NVD: AV:N/AC:L/Au:N/C:P/I:P/A:P
Understanding the Weakness (CWE)
Integrity,Confidentiality,Availability
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands
Buffer overflows often can be used to execute arbitrary code, which is usually outside the scope of the product's implicit security policy. This can often be used to subvert any other security service.
Availability
Technical Impact: Modify Memory; DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU)
Buffer overflows generally lead to crashes. Other attacks leading to lack of availability are possible, including putting the product into an infinite loop.
