According to the versions of the yajl package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - yajl-ruby is a C binding to the YAJL JSON parsing and generation library. 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. (CVE-2022-24795)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The version of rubygem-yajl-ruby installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2022-24795 advisory.
