CVE-2022-23204: Out-of-Bounds Read Vulnerability in Adobe Premiere Rush Revealing Sensitive Memory Information

Adobe Premiere Rush is a popular video editing application used by professionals and amateurs alike. In this article, we will dive deep into a newly discovered vulnerability, CVE-2022-23204, affecting Adobe Premiere Rush versions 2. and earlier. This vulnerability has the potential to expose sensitive memory information through an out-of-bounds read, which attackers could leverage to bypass security mitigations like Address Space Layout Randomization (ASLR). We will also provide links to original references, discuss the exploitation of this vulnerability, and present code snippets as examples.

Vulnerability Details

CVE-2022-23204 pertains to an out-of-bounds read vulnerability in Adobe Premiere Rush versions 2. and earlier. The vulnerability occurs when the application reads data past the end of an allocated memory buffer, resulting in a disclosure of potentially sensitive memory contents. In turn, this could give an attacker vital information about the system to design a more targeted exploit. This issue arises due to insufficient handling of maliciously crafted files, making the victim's system prone to attack.

Exploitation of CVE-2022-23204 requires user interaction, meaning a potential attacker must convince the victim to open a maliciously crafted file using the Adobe Premiere Rush application. Once opened, the attacker could gain vital system information to bypass ASLR and other security mitigations, making it easier to execute more complex attacks.

Code Snippet

Consider the following example, which represents a portion of code that could lead to an out-of-bounds read vulnerability:

#include <stdlib.h>
#include <string.h>

void vulnerable_function(char *user_data, size_t user_data_length) {
    char buffer[32];

    if (user_data_length > 32) {
        memcpy(buffer, user_data, user_data_length);
    }
}

In this example, if the user_data_length exceeds the size of the buffer array (32 bytes), an out-of-bounds read occurs when memcpy is called. This results in sensitive memory contents being unintentionally disclosed.

Mitigation and Patching

Adobe has acknowledged the vulnerability and published a security bulletin APSB22-09 addressing CVE-2022-23204. Users are strongly encouraged to update to the latest Adobe Premiere Rush version (2.1 or later) to mitigate the risk associated with this vulnerability.

For developers, it is vital to ensure that all data buffer sizes are checked and handled correctly before use. Consider using safe methods, like strncpy and memcpy_s, for copying memory contents to prevent out-of-bounds read vulnerabilities.

Conclusion and References

CVE-2022-23204 is a critical vulnerability affecting Adobe Premiere Rush versions 2. and earlier. Attackers could exploit this out-of-bounds read vulnerability to disclose sensitive system memory, potentially bypassing ASLR and other security mitigations in the process. To protect against this vulnerability, users should update their Adobe Premiere Rush software to version 2.1 or later.
