Adobe Systems today issued a significant update to its Acrobat and Acrobat Reader products for Windows and macOS, fixing 86 vulnerabilities, including multiple critical arbitrary code execution flaws.

The bugs consist of 22 out-of-bounds writes, 36 out-of-bounds reads, seven heap overflows, seven use-after-frees, three type confusions, one stack overflow, one double free, two integer overflows, three buffer errors, three untrusted pointer dereferences, and a security bypass.

In addition to code execution, some of these bugs can be exploited for information disclosure and privilege escalation.
