The 1.x branch and the 2.x branch of `yajl` contain an integer overflow which leads to subsequent heap memory corruption when dealing with large (~2GB) inputs. The reallocation logic at `yajl_buf.c#L64` may result in the `need` 32bit integer wrapping to 0 when `need` approaches a value of 0x80000000 (i.e. ~2GB of data), which results in a reallocation of buf->alloc into a small heap chunk. These integers are declared as `size_t` in the 2.x branch of `yajl`, which practically prevents the issue from triggering on 64bit platforms, however this does not preclude this issue triggering on 32bit builds on which `size_t` is a 32bit integer. Subsequent population of this under-allocated heap chunk is based on the original buffer size, leading to heap memory corruption. This vulnerability mostly impacts process availability. Maintainers believe exploitation for arbitrary code execution is unlikely. A patch is available and anticipated to be part of yajl-ruby version 1.4.2. As a workaround, avoid passing large inputs to YAJL."}],"affected":[{"vendor":"brianmario","product":"yajl-ruby","versions":[{"version":"<= 1.4.1","status":"affected"}]}],"references":[{"url":"https://github.com/brianmario/yajl-ruby/security/advisories/GHSA-jj47-x69x-mxrm"},{"url":"https://github.com/brianmario/yajl-ruby/commit/7168bd79b888900aa94523301126f968a93eb3a6"},{"url":"https://github.com/brianmario/yajl-ruby/blob/7168bd79b888900aa94523301126f968a93eb3a6/ext/yajl/yajl_buf.c#L64"},{"name":"[debian-lts-announce] 20230711 [SECURITY] [DLA 3492-1] yajl security update","tags":["mailing-list"],"url":"https://lists.debian.org/debian-lts-announce/2023/07/msg00013.html"},{"name":"FEDORA-2023-00572178e1","tags":["vendor-advisory"],"url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/KLE3C4CECEJ4EUYI56KXI6OWACWXX7WN/"},{"name":"FEDORA-2023-852b377773","tags":["vendor-advisory"],"url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YO32YDJ74DADC7CMJNLSLBVWN5EXGF5J/"},{"name":"[debian-lts-announce] 20230805 [SECURITY] [DLA 3516-1] burp security update","tags":["mailing-list"],"url":"https://lists.debian.org/debian-lts-announce/2023/08/msg00003.html"}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","attackVector":"NETWORK","attackComplexity":"HIGH","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH","baseScore":5.9,"baseSeverity":"MEDIUM"}}],"problemTypes":[{"descriptions":[{"type":"CWE","lang":"en","description":"CWE-122: Heap-based Buffer Overflow","cweId":"CWE-122"}]},{"descriptions":[{"type":"CWE","lang":"en","description":"CWE-190: Integer Overflow or Wraparound","cweId":"CWE-190"}]}],"source":{"advisory":"GHSA-jj47-x69x-mxrm","discovery":"UNKNOWN"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-03T04:20:50.514Z"},"title":"CVE Program Container","references":[{"url":"https://github.com/brianmario/yajl-ruby/security/advisories/GHSA-jj47-x69x-mxrm","tags":["x_transferred"]},{"url":"https://github.com/brianmario/yajl-ruby/commit/7168bd79b888900aa94523301126f968a93eb3a6","tags":["x_transferred"]},{"url":"https://github.com/brianmario/yajl-ruby/blob/7168bd79b888900aa94523301126f968a93eb3a6/ext/yajl/yajl_buf.c#L64","tags":["x_transferred"]},{"name":"[debian-lts-announce] 20230711 [SECURITY] [DLA 3492-1] yajl security update","tags":["mailing-list","x_transferred"],"url":"https://lists.debian.org/debian-lts-announce/2023/07/msg00013.html"},{"name":"FEDORA-2023-00572178e1","tags":["vendor-advisory","x_transferred"],"url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/KLE3C4CECEJ4EUYI56KXI6OWACWXX7WN/"},{"name":"FEDORA-2023-852b377773","tags":["vendor-advisory","x_transferred"],"url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YO32YDJ74DADC7CMJNLSLBVWN5EXGF5J/"},{"name":"[debian-lts-announce] 20230805 [SECURITY] [DLA 3516-1] burp security update","tags":["mailing-list","x_transferred"],"url":"https://lists.debian.org/debian-lts-announce/2023/08/msg00003.html"}]},{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2025-04-22T15:49:09.360664Z","id":"CVE-2022-24795","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2025-04-22T18:17:37.564Z"}}]}}
