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-\u0026gt;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.(CVE-2022-24795)","affected":[{"package":{"ecosystem":"openEuler:20.03-LTS-SP1","name":"yajl","purl":"pkg:rpm/openEuler/yajl\u0026distro=openEuler-20.03-LTS-SP1"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.1.0-16.oe1"}]}],"ecosystem_specific":{"aarch64":["yajl-2.1.0-16.oe1.aarch64.rpm","yajl-debugsource-2.1.0-16.oe1.aarch64.rpm","yajl-devel-2.1.0-16.oe1.aarch64.rpm","yajl-debuginfo-2.1.0-16.oe1.aarch64.rpm"],"src":["yajl-2.1.0-16.oe1.src.rpm"],"x86_64":["yajl-2.1.0-16.oe1.x86_64.rpm","yajl-debuginfo-2.1.0-16.oe1.x86_64.rpm","yajl-debugsource-2.1.0-16.oe1.x86_64.rpm","yajl-devel-2.1.0-16.oe1.x86_64.rpm"]}},{"package":{"ecosystem":"openEuler:20.03-LTS-SP3","name":"yajl","purl":"pkg:rpm/openEuler/yajl\u0026distro=openEuler-20.03-LTS-SP3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.1.0-16.oe1"}]}],"ecosystem_specific":{"aarch64":["yajl-2.1.0-16.oe1.aarch64.rpm","yajl-debuginfo-2.1.0-16.oe1.aarch64.rpm","yajl-debugsource-2.1.0-16.oe1.aarch64.rpm","yajl-devel-2.1.0-16.oe1.aarch64.rpm"],"src":["yajl-2.1.0-16.oe1.src.rpm"],"x86_64":["yajl-2.1.0-16.oe1.x86_64.rpm","yajl-debugsource-2.1.0-16.oe1.x86_64.rpm","yajl-debuginfo-2.1.0-16.oe1.x86_64.rpm","yajl-devel-2.1.0-16.oe1.x86_64.rpm"]}},{"package":{"ecosystem":"openEuler:22.03-LTS","name":"yajl","purl":"pkg:rpm/openEuler/yajl\u0026distro=openEuler-22.03-LTS"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.1.0-18.oe2203"}]}],"ecosystem_specific":{"aarch64":["yajl-devel-2.1.0-18.oe2203.aarch64.rpm","yajl-2.1.0-18.oe2203.aarch64.rpm","yajl-debuginfo-2.1.0-18.oe2203.aarch64.rpm","yajl-debugsource-2.1.0-18.oe2203.aarch64.rpm"],"src":["yajl-2.1.0-18.oe2203.src.rpm"],"x86_64":["yajl-2.1.0-18.oe2203.x86_64.rpm","yajl-debuginfo-2.1.0-18.oe2203.x86_64.rpm","yajl-devel-2.1.0-18.oe2203.x86_64.rpm","yajl-debugsource-2.1.0-18.oe2203.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/en/security/safety-bulletin/detail.html?id=openEuler-SA-2022-1912"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-24795"}],"database_specific":{"severity":"High"}}
