CVSS: 7.8EPSS: 0%CPEs: 6EXPL: 1CVE-2022-38784 – poppler: integer overflow in JBIG2 decoder using malformed files
https://notcve.org/view.php?id=CVE-2022-38784
Poppler prior to and including 22.08.0 contains an integer overflow in the JBIG2 decoder (JBIG2Stream::readTextRegionSeg() in JBIGStream.cc). Processing a specially crafted PDF file or JBIG2 image could lead to a crash or the execution of arbitrary code. This is similar to the vulnerability described by CVE-2022-38171 in Xpdf. Poppler versiones anteriores a 22.08.0 incluyéndola, contiene un desbordamiento de enteros en el descodificador JBIG2 (la función JBIG2Stream::readTextRegionSeg() en el archivo JBIGStream.cc). El procesamiento de un archivo PDF o una imagen JBIG2 especialmente diseñados podría conllevar a un bloqueo o una ejecución de código arbitrario. • http://www.openwall.com/lists/oss-security/2022/09/02/11 https://github.com/jeffssh/CVE-2021-30860 https://github.com/zmanion/Vulnerabilities/blob/main/CVE-2022-38171.md https://gitlab.freedesktop.org/poppler/poppler/-/merge_requests/1261/diffs?commit_id=27354e9d9696ee2bc063910a6c9a6b27c5184a52 https://lists.debian.org/debian-lts-announce/2022/09/msg00030.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BGY72LBJMFAKQWC2XH4MRPIGPQLXTFL6 https://lists.fedoraproject&# • CWE-190: Integer Overflow or Wraparound •

res_pjsip_t38 in Sangoma Asterisk 16.x before 16.16.2, 17.x before 17.9.3, and 18.x before 18.2.2, and Certified Asterisk before 16.8-cert7, allows an attacker to trigger a crash by sending an m=image line and zero port in a response to a T.38 re-invite initiated by Asterisk. This is a re-occurrence of the CVE-2019-15297 symptoms but not for exactly the same reason. The crash occurs because there is an append operation relative to the active topology, but this should instead be a replace operation. La función res_pjsip_t38 en Sangoma Asterisk versiones 16.x anteriores a 16.16.2, 17.x anteriores a 17.9.3, y 18.x anteriores a 18.2.2, y Certified Asterisk anteriores a 16.8-cert7, permite a un atacante desencadenar un fallo mediante el envío de una línea m=image y un puerto cero en una respuesta a una Re invitación T.38 iniciada por Asterisk. Se trata de una reaparición de los síntomas de la CVE-2019-15297 pero no exactamente por el mismo motivo. • https://downloads.asterisk.org/pub/security/AST-2021-006.html https://lists.debian.org/debian-lts-announce/2022/11/msg00021.html https://www.debian.org/security/2022/dsa-5285 • CWE-476: NULL Pointer Dereference •

telnetd in GNU Inetutils through 2.3, MIT krb5-appl through 1.0.3, and derivative works has a NULL pointer dereference via 0xff 0xf7 or 0xff 0xf8. In a typical installation, the telnetd application would crash but the telnet service would remain available through inetd. However, if the telnetd application has many crashes within a short time interval, the telnet service would become unavailable after inetd logs a "telnet/tcp server failing (looping), service terminated" error. NOTE: MIT krb5-appl is not supported upstream but is shipped by a few Linux distributions. The affected code was removed from the supported MIT Kerberos 5 (aka krb5) product many years ago, at version 1.8. telnetd en GNU Inetutils versiones hasta 2.3, MIT krb5-appl versiones hasta 1.0.3, y trabajos derivados presenta una desreferencia de puntero NULL por medio de 0xff 0xf7 o 0xff 0xf8. • https://git.hadrons.org/cgit/debian/pkgs/inetutils.git/commit/?id=113da8021710d871c7dd72d2a4d5615d42d64289 https://lists.debian.org/debian-lts-announce/2022/11/msg00033.html https://lists.gnu.org/archive/html/bug-inetutils/2022-08/msg00002.html https://pierrekim.github.io/blog/2022-08-24-2-byte-dos-freebsd-netbsd-telnetd-netkit-telnetd-inetutils-telnetd-kerberos-telnetd.html • CWE-476: NULL Pointer Dereference •
