The vulnerability identified as CVE-2024-48958 affects libarchive before version 3.7.5. Specifically, the function execute_filter_delta located in archive_read_support_format_rar.c allows for out-of-bounds access when processing specially crafted archive files. This occurs because the source pointer can move beyond the destination pointer, leading to potential memory corruption and unauthorized access.
With a CVSS score of 7.8, this vulnerability is classified as high severity, indicating significant risk to organizations leveraging affected versions of libarchive. The vulnerability's exploitability is currently assessed as high, necessitating immediate attention from security teams.
Risk to organizations includes potential unauthorized access and data corruption due to the out-of-bounds access. The vulnerability requires user interaction to exploit, which increases the risk profile if users handle untrusted archive files.
Organizations should prioritize patching immediately to mitigate the risk associated with this vulnerability.
Vulnerability Details
CVE-2024-48958 is characterized by the ability to execute_filter_delta in libarchive, allowing for out-of-bounds memory access through crafted archive files. The CVSS version 3.1 score is 7.8, which indicates a high severity level due to the potential for significant confidentiality, integrity, and availability impacts. Affected versions of libarchive include all versions prior to 3.7.5, emphasizing the importance of updating to the latest release.
Technical Analysis
The root cause of CVE-2024-48958 lies in the improper handling of pointers within the execute_filter_delta function. An attacker could craft an archive file that, when processed, causes the source pointer to exceed its allocated bounds. This vulnerability has a low attack complexity, requires no privileges, and necessitates user interaction to initiate the exploit. The potential impacts on confidentiality, integrity, and availability are all rated as high, indicating severe consequences if exploited.
Risk & Impact Analysis
Organizations using libarchive must understand the risks associated with this vulnerability. The potential blast radius includes any system that processes untrusted archive files, increasing the urgency to address this vulnerability. Given the CVSS score, organizations should schedule remediation as a priority to protect sensitive data and maintain system integrity.
