An update of the erlang package has been released.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Stack-based Buffer Overflow vulnerability in Erlang OTP (erl_interface) allows Stack-based Buffer     Overflow. This vulnerability is associated with program file lib/erl_interface/src/misc/ei_printterm.c and     program routine ei_s_print_term. The C function ei_s_print_term uses an internal 2000-character stack     buffer to format terms. When called with an encoded Erlang term containing a very large integer (encoded     representation exceeding 2000 characters), the buffer overflows. The overflow bytes are restricted to the     ASCII values of 0-9 and A-F, which limits exploitation to Denial of Service. The companion function     ei_print_term, which prints directly to a FILE instead of a memory buffer, does not contain this bug. This     issue affects OTP from OTP 17.0 before OTP 29.0.2, OTP 28.5.0.2 and OTP 27.3.4.13, corresponding to     erl_interface from 3.7.16 before 5.8.1, 5.7.0.1 and 5.5.2.1. (CVE-2026-49760)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the d87de755-64d4-11f1-ab11-4c526214c986 advisory.

    https://github.com/erlang/otp/security/advisories/GHSA-xcxj-5pg2-v72j reports:
    Fixed a stack overflow in ei_s_print_term in erl_interface               for very large integer terms (more than 2000 hexadecimal digits               long).

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

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

    Multiple vulnerabilities were discovered in Erlang/OTP, a concurrent,     real-time, distributed functional language, which may result in denial of     service, information disclosure, authentication and certificate validation     bypass, or the execution of arbitrary code. These vulnerbilities affect a     wide range of components: TLS and certificate validation (ssl, public_key),     SSH (ssh), network clients and servers (inets, ftp, epmd, kernel),     runtime and libraries (erts, erl_interface, stdlib, megaco).

    Several of these fixes tighten checks that were previously too permissive,     and can cause configurations that worked before to stop working. The most     likely to be noticed are:

     - TLS clients using verify_peer, which is the default, now reject        certificates that carry no subjectAltName extension; the        customize_hostname_check option does not restore the old behaviour.

     - Erlang distribution over TLS with the kernel 'check_ip' option now        enforces the check that was previously a no-op, so clusters whose nodes        are not on the same subnet lose distribution connectivity until the        option is unset.

     - TLS clients that request OCSP stapling now fail the handshake when the        server provides no stapled response.

     - Clients using TLS 1.2 or earlier now abort the handshake if the server        sends an ALPN extension that the client did not advertise.

     - DNS queries made through inet_res now use randomised source ports

    For the stable distribution (trixie), these problems have been fixed in     version 1:27.3.4.1+dfsg-1+deb13u3.

    We recommend that you upgrade your erlang packages.
