Adobe Illustrator and Bridge, Also PatchedДЄdditional Adobe products were also part of the vendorвЂ™s roundup of fixes, Bridge, Framemaker Dimension and Illustrator.ДЇour critical bugsВ in AdobeвЂ™s Bridge, a free app for managing digital assets, were patched.В These include a heap-based buffer-overflow flaw (CVE-2021-28624), improper input-validation vulnerability (CVE-2021-35991) and two arbitrary code-execution bugs (CVE-2021-35989, CVE-2021-35990).ДЄ heap-based buffer overflow allows for arbitrary code execution by an adversary causing either a program crash, infinite loop restart of a program or a type of denial-of-service attack based on CPU or memory overconsumption. вЂњThe product uses a fixed or controlled search path to find resources, but one or more locations in that path can be under the control of unintended actorsвЂ¦ In some cases, the attack can be conducted remotely, such as when SMB or WebDAV network shares are used,вЂќ according to a MITRE description of the vulnerability type. The security bulletin links to a generic description of the flaw which states: ItвЂ™s unclear how the weakness was introduced to Adobe Acrobat. The vulnerability class also goes by the names DLL preloading, insecure library loading and dependency confusion. One of the more interesting critical bugs patched is a type of vulnerability called an вЂњuncontrolled search path elementвЂќ flaw (CVE-2021-28636). Two of the most serious Acrobat vulnerabilities are use-after-free flaws ( CVE-2021-28641, CVE-2021-28639) that, in a worst case scenario, allow an adversary to execute code arbitrarily on targeted systems or just create application crashes. In all, Adobe patched 20 Acrobat bugs, with nine rated important. Adobe also patched Acrobat DC, Acrobat DC Reader, Acrobat Reader 2017 and Acrobat 2017. The free Acrobat Reader 2020 and PDF-creation and editing software Acrobat 2020 were among the list of those programs with critical bugs patched. Adobe added however that it was not aware of any abuse of the bugs in the wild. In a Tuesday security bulletin, which included patches for all flaws, the company reported that Windows and macOS versions of Acrobat were equally vulnerable.
