Welcome to our in-depth analysis of a significant cybersecurity vulnerability identified as CVE-2024-5171. This security issue affects libaom, a library widely used in media applications for advanced video coding. The severity of this flaw is high, with a critical rating and a CVSS score of 9.8, indicating an urgent need for attention and action.
Libaom is an open-source library used for AV1 video encoding and decoding. AV1 is an advanced, highly efficient video format gaining traction across various platforms for its ability to deliver superior video quality at reduced bandwidth usage. As such, libaom is integrated into numerous multimedia processing applications, making it a critical component in both consumer and enterprise-grade software.
The vulnerability stems from an integer overflow within the internal function img_alloc_helper used by libaom. This function, crucial for managing video image memory, exposes the system to heap buffer overflow issues if exploited. Such vulnerabilities occur when a program attempts to write data outside the memory boundaries allocated for it, which can lead to crashes, corruption of data, or even the execution of malicious code.
Specifically, CVE-2024-5171 can be triggered in three different ways:
aom_img_alloc() when called with excessively large values for d_w (width), d_h (height), or align parameters.aom_img_wrap() with similarly large values for width, height, or alignment.aom_img_alloc_with_border(), where, in addition to width and height, the size_align or border parameters can also lead to overflow conditions.These vulnerabilities highlight the importance of careful parameter validation within software applications, especially those dealing with memory management in multimedia environments. The potential impact of exploiting these vulnerabilities includes unauthorized execution of arbitrary code, authorized bypassing, denial of service (DoS), information disclosure, and system compromise.
Addressing this vulnerability is critical. Organizations and users reliant on software involving libaom should prioritize updating their systems. For those utilizing Linux systems, it’s essential to employ a vigilant patch management strategy. We strongly recommend visiting LinuxPatch, a dedicated patch management platform for Linux servers, to ensure your systems are safeguarded against vulnerabilities like CVE-2024-5171.
