Apache Guacamole 1.1.0 and older do not properly validate datareceived from RDP servers via static virtual channels. If a userconnects to a malicious or compromised RDP server, specially-craftedPDUs could result in disclosure of information within the memory ofthe guacd process handling the connection. Apache Guacamole versiones 1.1.0 y anteriores, no comprueban apropiadamente los datos recibidos desde servidores RDP por medio de canales virtuales estáticos. Si un usuario se conecta a un servidor RDP malicioso o comprometido, las PDU especialmente diseñadas podrían resultar en divulgación de información dentro de la memoria del proceso guacd que maneja la conexión • https://kb.pulsesecure.net/articles/Pulse_Security_Advisories/SA44525 https://lists.apache.org/thread.html/r066543f0565e97b27c0dfe27e93e8a387b99e1e35764000224ed96e7%40%3Cuser.guacamole.apache.org%3E https://lists.apache.org/thread.html/r1125f3044a0946d1e7e6f125a6170b58d413ebd4a95157e4608041c7%40%3Cannounce.apache.org%3E https://lists.apache.org/thread.html/r181b1d5b1acb31cfa69f41b2c86ed3a2cb0b5bc09c2cbd31e9e7c847%40%3Cuser.guacamole.apache.org%3E https://lists.apache.org/thread.html/r3f071de70ea1facd3601e0fa894e6cadc960627ee7199437b5a56f7f%40%3Cannounce.apache.org%3E https://lists • CWE-20: Improper Input Validation •
CVE-2020-15503 – LibRaw: lack of thumbnail size range check can lead to buffer overflow
https://notcve.org/view.php?id=CVE-2020-15503
LibRaw before 0.20-RC1 lacks a thumbnail size range check. This affects decoders/unpack_thumb.cpp, postprocessing/mem_image.cpp, and utils/thumb_utils.cpp. For example, malloc(sizeof(libraw_processed_image_t)+T.tlength) occurs without validating T.tlength. LibRaw versiones anteriores a 0.20-RC1, carece de una comprobación de rango de tamaño de miniaturas. Esto afecta a los archivos decoders/unpack_thumb.cpp, postprocessing/mem_image.cpp, y utils/thumb_utils.cpp. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00075.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00001.html https://github.com/LibRaw/LibRaw/commit/20ad21c0d87ca80217aee47533d91e633ce1864d https://github.com/LibRaw/LibRaw/compare/0.20-Beta3...0.20-RC1 https://lists.debian.org/debian-lts-announce/2022/11/msg00042.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/7HM2DS6HA4YZREI3BYGS75M6D76WMW62 https://lists.fedoraproject.org/ • CWE-20: Improper Input Validation CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
CVE-2020-5238 – Denial of service in table parsing in cmark-gfm
https://notcve.org/view.php?id=CVE-2020-5238
The table extension in GitHub Flavored Markdown before version 0.29.0.gfm.1 takes O(n * n) time to parse certain inputs. An attacker could craft a markdown table which would take an unreasonably long time to process, causing a denial of service. This issue does not affect the upstream cmark project. The issue has been fixed in version 0.29.0.gfm.1. La extensión de tabla en GitHub Flavored Markdown anterior a la versión 0.29.0.gfm.1 toma un tiempo O(n*n) en analizar determinadas entradas. • https://github.com/github/cmark-gfm/commit/85d895289c5ab67f988ca659493a64abb5fec7b4 https://github.com/github/cmark-gfm/security/advisories/GHSA-7gc6-9qr5-hc85 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TCDHBTUFIOYRIS5HAS6PZNBNMB7IOAX3 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WMQFOQQCWOAMQ4I2XIVCVOXXIJ75HDCW https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ZGJH2A4VAV54X6NSCNNGSEIGIIY5N2VR https://access.redhat& • CWE-20: Improper Input Validation •

CVE-2017-18922 – libvncserver: websocket decoding buffer overflow
https://notcve.org/view.php?id=CVE-2017-18922
It was discovered that websockets.c in LibVNCServer prior to 0.9.12 did not properly decode certain WebSocket frames. A malicious attacker could exploit this by sending specially crafted WebSocket frames to a server, causing a heap-based buffer overflow. Se detectó que el archivo websockets.c en LibVNCServer versiones anteriores a 0.9.12, no decodificaba apropiadamente determinados tramas de WebSocket. Un atacante malicioso podría explotar esto mediante el envío de tramas de WebSocket especialmente diseñadas hacia un servidor, causando un desbordamiento del búfer en la región heap de la memoria A flaw was found in libvncserver. A heap-based buffer overflow within the websocket decoding functionality is possible, which can lead to exploitation by a malicious attacker to overwrite a function pointer. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00028.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00033.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00055.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00066.html http://www.openwall.com/lists/oss-security/2020/06/30/3 https://bugzilla.redhat.com/show_bug.cgi?id=1852356 https://cer • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
