A detailed analysis of CVE-2023-45681 outlining the impact, technical details, and mitigation strategies.
Understanding CVE-2023-45681
Exploring the vulnerability found in the 'stb_vorbis' library which can lead to out-of-bounds heap buffer write.
What is CVE-2023-45681?
The CVE-2023-45681 vulnerability stems from an out-of-bounds write issue in the 'stb_vorbis' library, a single file MIT licensed library used for processing ogg vorbis files. By exploiting this flaw, an attacker can trigger a memory write past an allocated heap buffer, potentially leading to code execution.
The Impact of CVE-2023-45681
The impact of this vulnerability is significant as it may allow an attacker to execute arbitrary code by manipulating memory allocation and causing integer overflows in critical functions within the library.
Technical Details of CVE-2023-45681
An in-depth look at the vulnerability's description, affected systems, versions, and exploitation mechanism.
Vulnerability Description
The root cause of CVE-2023-45681 lies in a potential integer overflow in 'sizeof(char*) * (f->comment_list_length)' within the 'stb_vorbis' library, affecting the 'start_decoder' function. This integer overflow can result in 'setup_malloc' allocating insufficient memory, leading to further vulnerabilities that can be exploited by attackers.
Affected Systems and Versions
The 'stb_vorbis' library versions up to 1.22 are impacted by this vulnerability, making systems utilizing these versions susceptible to exploitation.
Exploitation Mechanism
By leveraging the identified integer overflow vulnerabilities, an attacker can craft malicious files to trigger memory overflows, eventually allowing for code execution through precise manipulation of memory allocation methods.
