CVE-2023-48706
Description
A heap use-after-free flaw was found in the vim package. When executing a :s command for the first time and using a sub-replace-special atom inside the substitution part, it is possible that the recursive :s call causes memory to be freed, which may later then be accessed by the initial :s command. This issue may result in Vim crashing.
Statement
Red Hat considers this as a low impact since it requires the command to be run for the very first time and access to the shell in order to run the payload.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert: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).
The following CVSS metrics and score provided are preliminary and subject to review.
