CVE-2013-0640
CVE-2013-0640 is a security flaw in Adobe Reader and Acrobat, Adobe’s software for opening and editing PDFs. Opening a booby-trapped file can let an attacker run their own code through Adobe Reader and Acrobat. The US Cybersecurity and Infrastructure Security Agency (CISA) added it to its catalog of flaws known to be used in attacks on 3 Mar 2022.[1]
Adobe Reader and Acrobat is in things households have, such as phones, computers, browsers and everyday apps, so the fix matters at home as much as at work.
Description
CISA calls it a memory corruption in Adobe Reader and Acrobat. In its words: “An memory corruption vulnerability exists in the acroform.dll in Adobe Reader that allows an attacker to perform remote code execution.”[1]
The CVE record adds: “Adobe Reader and Acrobat 9.x before 9.5.4, 10.x before 10.1.6, and 11.x before 11.0.02 allow remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted PDF document, as exploited in the wild in February 2013.”[2]
The underlying weakness is out-of-bounds write (CWE-787), in MITRE’s list of common software weaknesses.
It scores 7.8 out of 10 on the Common Vulnerability Scoring System, which rates it high, scored by NVD using CVSS 3.1.[2]
Affected versions
NVD’s record doesn’t list version ranges for it. CISA names the product as Adobe Reader and Acrobat.
Every device with Adobe Reader and Acrobat needs the update.
Exploitation
CISA added it to its catalog of known exploited vulnerabilities on 3 Mar 2022, 3,304 days after it was made public. CISA lists a flaw only when it has reliable evidence of it being exploited, and gave US federal agencies until 24 Mar 2022 to fix it.[1]
FIRST’s Exploit Prediction Scoring System, which estimates how likely a flaw is to be used in attacks in the next 30 days from what it sees across the internet, puts it at 87%. That’s in the top 1% of the flaws it scores.[3]
CISA assesses it as not automatable: each attack takes some work.
CISA doesn’t say who was attacked, or how.
Fix
CISA’s required action: “Apply updates per vendor instructions.”[1]
- Update Adobe Reader and Acrobat now.Install the latest update from Adobe on every device that has it, and restart when asked. Then turn on automatic updates, so the next fix arrives on its own.
- If there’s no update, stop using it.CISA’s advice when a flaw being used in attacks has no fix is to stop using the product until it does.
