{"id":"ALPINE-CVE-2022-41903","details":"Git is distributed revision control system. `git log` can display commits in an arbitrary format using its `--format` specifiers. This functionality is also exposed to `git archive` via the `export-subst` gitattribute. When processing the padding operators, there is a integer overflow in `pretty.c::format_and_pad_commit()` where a `size_t` is stored improperly as an `int`, and then added as an offset to a `memcpy()`. This overflow can be triggered directly by a user running a command which invokes the commit formatting machinery (e.g., `git log --format=...`). It may also be triggered indirectly through git archive via the export-subst mechanism, which expands format specifiers inside of files within the repository during a git archive. This integer overflow can result in arbitrary heap writes, which may result in arbitrary code execution. The problem has been patched in the versions published on 2023-01-17, going back to v2.30.7. Users are advised to upgrade. Users who are unable to upgrade should disable `git archive` in untrusted repositories. If you expose git archive via `git daemon`, disable it by running `git config --global daemon.uploadArch false`.","modified":"2026-08-27T22:17:55.830058038Z","published":"2023-01-17T23:15:15.690Z","upstream":["CVE-2022-41903"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2022-41903"}],"affected":[{"package":{"name":"git","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/git?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.31.0"},{"fixed":"2.32.5-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2022-41903.json"}},{"package":{"name":"git","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/git?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.31.0"},{"fixed":"2.34.6-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2022-41903.json"}},{"package":{"name":"git","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/git?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.31.0"},{"fixed":"2.36.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2022-41903.json"}},{"package":{"name":"git","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/git?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.31.0"},{"fixed":"2.38.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2022-41903.json"}},{"package":{"name":"git","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/git?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.31.0"},{"fixed":"2.39.1-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2022-41903.json"}},{"package":{"name":"git","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/git?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.31.0"},{"fixed":"2.39.1-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2022-41903.json"}},{"package":{"name":"git","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/git?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.31.0"},{"fixed":"2.39.1-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2022-41903.json"}},{"package":{"name":"git","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/git?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.31.0"},{"fixed":"2.39.1-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2022-41903.json"}},{"package":{"name":"git","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/git?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.31.0"},{"fixed":"2.39.1-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2022-41903.json"}},{"package":{"name":"git","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/git?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.31.0"},{"fixed":"2.39.1-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2022-41903.json"}},{"package":{"name":"git","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/git?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.31.0"},{"fixed":"2.39.1-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2022-41903.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
