The version of expat installed on the remote host is prior to 2.1.0-15. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2026-3170 advisory.

    In libexpat before 2.7.4, the doContent function does not properly determine the buffer size bufSize     because there is no integer overflow check for tag buffer reallocation. (CVE-2026-25210)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

The version of thunderbird installed on the remote host is prior to 140.7.1-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2026-3171 advisory.

    HarfBuzz is a text shaping engine. Prior to version 12.3.0, a null pointer dereference vulnerability     exists in the SubtableUnicodesCache::create function located in src/hb-ot-cmap-table.hh. The function     fails to check if hb_malloc returns NULL before using placement new to construct an object at the returned     pointer address. When hb_malloc fails to allocate memory (which can occur in low-memory conditions or when     using custom allocators that simulate allocation failures), it returns NULL. The code then attempts to     call the constructor on this null pointer using placement new syntax, resulting in undefined behavior and     a Segmentation Fault. This issue has been patched in version 12.3.0. (CVE-2026-22693)

    LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable     Network Graphics) raster image files. From 1.6.51 to 1.6.53, there is a heap buffer over-read in the     libpng simplified API function png_image_finish_read when processing interlaced 16-bit PNGs with 8-bit     output format and non-minimal row stride. This is a regression introduced by the fix for CVE-2025-65018.
    This vulnerability is fixed in 1.6.54. (CVE-2026-22695)

    LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable     Network Graphics) raster image files. From 1.6.26 to 1.6.53, there is an integer truncation in the libpng     simplified write API functions png_write_image_16bit and png_write_image_8bit causes heap buffer over-read     when the caller provides a negative row stride (for bottom-up image layouts) or a stride exceeding 65535     bytes. The bug was introduced in libpng 1.6.26 (October 2016) by casts added to silence compiler warnings     on 16-bit systems. This vulnerability is fixed in 1.6.54. (CVE-2026-22801)
