AI-suggested
Red Hat has released updated packages including libmodulemd-2.15.4-1.hum1 that fix this vulnerability. Applying this update mitigates the issue. Additionally, users should avoid parsing attacker-controlled compressed module metadata in rpmio-enabled builds. If compressed input is necessary, decompress outside the process with strict size quotas or reject files exceeding conservative decompressed size limits before passing to libmodulemd. Building libmodulemd without rpmio support also removes the affected code path.
Description
A moderate availability vulnerability exists in libmodulemd when rpmio support is enabled. The flaw allows an attacker to supply a highly compressible compressed YAML file that triggers excessive CPU and memory consumption during decompression, leading to denial of service. This issue affects environments that parse attacker-controlled compressed module metadata with rpmio enabled. Confidentiality and integrity impacts are not established. Red Hat has released an update including libmodulemd-2.15.4-1.hum1 to address this issue.
