Exploitability
| CWE ID | Description |
|---|---|
| CWE-119 | The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data. |
| CWE-121 | A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a stack-based buffer overflow in the parseQuota function of the dcmqrscp component in DCMTK versions up to 3.6.5. It occurs due to improper handling of the StorageQuota argument, which can be manipulated to cause the overflow. Exploiting this requires local access to the system. The issue has been publicly disclosed and fixed in version 3.6.6.
How can this vulnerability impact me? :
The vulnerability can lead to a stack-based buffer overflow, which may allow an attacker with local access to compromise the integrity, confidentiality, and availability of the affected system. This could result in unauthorized code execution or system crashes.
What immediate steps should I take to mitigate this vulnerability?
Upgrade the affected DCMTK component to version 3.6.6, as this version contains the fix for the vulnerability in the parseQuota function of dcmqrscp. This upgrade is sufficient to mitigate the issue.
