CVSS 2.0
7.8
HighMetricsAV:N/AC:L/Au:N/C:N/I:N/A:C
Name of the Vulnerable Software and Affected Versions
com.fasterxml.jackson.dataformat:jackson-dataformat-cbor versions 0 through 2.11.4
com.fasterxml.jackson.dataformat:jackson-dataformat-cbor versions 2.12.0-rc1 through 2.12.1
Description
The issue is related to the allocation of unlimited memory in the com.fasterxml.jackson.dataformat:jackson-dataformat-cbor package of the jackson-dataformats-binary library. This can be exploited by a remote attacker to cause a denial of service. The unchecked allocation of a byte buffer can cause a java.lang.OutOfMemoryError exception.
Recommendations
For com.fasterxml.jackson.dataformat:jackson-dataformat-cbor versions 0 through 2.11.4, update to version 2.11.4 or later.
For com.fasterxml.jackson.dataformat:jackson-dataformat-cbor versions 2.12.0-rc1 through 2.12.1, update to version 2.12.1 or later.
As a temporary workaround, consider restricting the allocation of byte buffers to prevent the java.lang.OutOfMemoryError exception.
