SCA: security update for yajl-ruby (GHSA-jj47-x69x-mxrm)

high Tenable Self-Hosted Container Security Plugin ID 416404

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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)
