{"id":"BIT-powershell-2020-8927","summary":"Buffer overflow in Brotli library","details":"A buffer overflow exists in the Brotli library versions prior to 1.0.8 where an attacker controlling the input length of a \"one-shot\" decompression request to a script can trigger a crash, which happens when copying over chunks of data larger than 2 GiB. It is recommended to update your Brotli library to 1.0.8 or later. If one cannot update, we recommend to use the \"streaming\" API as opposed to the \"one-shot\" API, and impose chunk size limits.","aliases":["BIT-brotli-2020-8927","BIT-dotnet-2020-8927","BIT-dotnet-sdk-2020-8927","CVE-2020-36846","CVE-2020-8927","GHSA-5v8v-66v8-mwm7","GO-2025-3726","PYSEC-2020-29","RUSTSEC-2021-0131","RUSTSEC-2021-0132"],"modified":"2025-09-04T19:11:59.025292Z","published":"2025-09-04T17:48:34.485Z","database_specific":{"cpes":["cpe:2.3:a:microsoft:powershell:*:*:*:*:*:*:*:*"],"severity":"Medium"},"references":[{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00108.html"},{"type":"WEB","url":"https://github.com/google/brotli/releases/tag/v1.0.9"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2020/12/msg00003.html"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/356JOYTWW4BWSZ42SEFLV7NYHL3S3AEH/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4TOGTZ2ZWDH662ZNFFSZVL3M5AJXV6JF/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/J4E265WKWKYMK2RYYSIXBEGZTDY5IQE6/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/M4VCDOJGL6BK3HB4XRD2WETBPYX2ITF6/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MMBKACMLSRX7JJSKBTR35UOEP2WFR6QP/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MQLM7ABVCYJLF6JRPF3M3EBXW63GNC27/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/W23CUADGMVMQQNFKHPHXVP7RPZJZNN6I/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WW62OZEY2GHJL4JCOLJRBSRETXDHMWRK/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ZXEQ3GQVELA2T4HNZG7VPMS2HDVXMJRG/"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-8927"},{"type":"WEB","url":"https://usn.ubuntu.com/4568-1/"},{"type":"WEB","url":"https://www.debian.org/security/2020/dsa-4801"}],"affected":[{"package":{"name":"powershell","ecosystem":"Bitnami","purl":"pkg:bitnami/powershell"},"ranges":[{"type":"SEMVER","events":[{"introduced":"7.0.0"},{"fixed":"7.0.9"},{"introduced":"7.1.0"},{"fixed":"7.1.6"},{"introduced":"7.2.0"},{"fixed":"7.2.2"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/powershell/BIT-powershell-2020-8927.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L"}]}],"schema_version":"1.7.3"}
