Adobe Says Critical PDF Reader Zero-Day Being Exploited

Software maker Adobe on Tuesday raised an alarm about new in-the-wild zero-day attacks hitting users of its widely deployed Adobe Acrobat and Reader product. As part of its scheduled batch of Patch Tuesday updates, Adobe warned that hackers are exploiting a remotely exploitable vulnerability — CVE-2023-26369 — to launch code execution attacks. Adobe describes the flaw as an out-of-bounds write memory safety issue affecting both Windows and macOS installations. “Successful exploitation could lead to arbitrary code execution. Adobe is aware that CVE-2023-26369 has been exploited in the wild in limited attacks targeting Adobe Acrobat and Reader,” the company said in an advisory. Adobe did not specify which operating system is being targeted by in-the-wild attackers. The Adobe Acrobat and Reader patch headlines a Patch Tuesday release that provides fixes for at least five documented flaws across multiple products. The company also pushed out a security update for Adobe Connect to fix a pair of bugs that could be exploited to launch arbitrary code execution attacks.
