Echo: aspell: security update to 0.60.8.1-4+e1

medium Tenable Cloud Security Plugin ID 474770

Description

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

- GNU Aspell 0.60.8.2 (first vulnerable version is not known) contains a heap-based buffer overflow write
(CWE-122) in its read-only dictionary loader. String::reserve() in common/string.hpp computes its capacity
check with a signed int ((int)s + 1), so a requested size of 0x7FFFFFFF wraps negative and the backing
buffer is never grown. ReadOnlyDict::load() in modules/speller/default/readonly_ws.cpp passes the
unvalidated 32-bit size fields from a .rws dictionary header into this path, so a crafted .rws file with a
valid endian marker (12345678) and an oversized length field (e.g. lang_name_size = 0x7FFFFFFF) causes
attacker-controlled data to be written out of bounds past an undersized heap allocation. An attacker who
induces a victim to load a malicious dictionary — for example via aspell dump master <file> — can corrupt
heap memory, resulting in denial of service and potentially code execution. Fixed in b830b6e and will be
fixed in release 0.60.8.3. (CVE-2026-103658)

Solution

Update the aspell library and its related packages to version 0.60.8.1-4+e1 or later.
