    Package        : burp     Version        : 2.1.32-2+deb10u1     CVE ID         : CVE-2017-16516 CVE-2022-24795 CVE-2023-33460     Debian Bug     : 1040036

    Multiple vulnerabilities have been found in the version of yajl bundled     with burp, a simple cross-platform network BackUp and Restore Program.
    yajl is a JSON parser and small validating JSON generator.

    CVE-2017-16516

      When a crafted JSON file is supplied to yajl, the process might       crash with a SIGABRT in the yajl_string_decode function in       yajl_encode.c.  This potentially results in a denial of service.

    CVE-2022-24795

      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.

    CVE-2023-33460

      There's a memory leak in yajl 2.1.0 with use of yajl_tree_parse       function, which potentially cause the server to run out of memory and       crash.

    For Debian 10 buster, this problem has been fixed in version     2.1.32-2+deb10u1.

    We recommend that you upgrade your burp packages.

The remote Ubuntu 16.04 ESM / 18.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6233-1 advisory.

    It was discovered that YAJL was not properly performing bounds checks when decoding a string with escape     sequences. If a user or automated system using YAJL were tricked into processing specially crafted input,     an attacker could possibly use this issue to cause a denial of service (application abort).

    Multiple vulnerabilties have been found in yajl, a JSON parser / small     validating JSON generator# written in ANSI C, which potentially can     cause memory corruption or DoS.

    The CVE-20117-16516 had been addressed already in DLA-3478, however the     fix has been found to be incomplete as it missed an additional memory     leak.  This update fixes that problem.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

A vulnerability was found in ruby-yajl, an interface to Yajl, a JSON stream-based parser library. When a crafted JSON file is supplied to Yajl::Parser.new.parse, the whole ruby process crashes with a SIGABRT in the yajl_string_decode function in yajl_encode.c. This may result in a denial of service.

For Debian 7 'Wheezy', these problems have been fixed in version 1.1.0-2+deb7u1.

We recommend that you upgrade your ruby-yajl packages.
