What is CVE-2021-43757?

Adobe Media Encoder, specifically versions 22.0 and 15.4.2 (and earlier), is susceptible to an out-of-bounds read vulnerability. This security issue can potentially allow attackers to disclose sensitive information from memory. The exploitation process requires user interaction, as a victim must open a specially crafted 3GP file. Due to this flaw, traditional protections like Address Space Layout Randomization (ASLR) may be bypassed, increasing the risk of confidentiality breaches.
