Adobe Illustrator version 25.2.3 (and earlier) is affected by an Use-after-free vulnerability when parsing a specially crafted file. An unauthenticated attacker could leverage this vulnerability to read arbitrary file system information in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
