*** Pendiente de traducción *** An Improper Input Validation vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS).<br /> <br /> When certain specific crafted BGP UPDATE messages are received over an established BGP session, one BGP session may be torn down with an UPDATE message error, or the issue may propagate beyond the local system which will remain non-impacted, but may affect one or more remote systems. This issue is exploitable remotely as the crafted UPDATE message can propagate through unaffected systems and intermediate BGP speakers.<br /> Continuous receipt of the crafted BGP UPDATE messages will create a sustained Denial of Service (DoS) condition for impacted devices.<br /> <br /> This issue affects eBGP and iBGP, in both IPv4 and IPv6 implementations. This issue requires a remote attacker to have at least one established BGP session.<br /> Improper Input Validation, Denial of Service vulnerability in Juniper Networks, Inc. Junos OS (BGP, rpd modules), Juniper Networks, Inc. Junos OS Evolved (BGP, rpd modules) allows Fuzzing.This issue affects <br /> <br /> Junos OS: <br /> <br /> <br /> <br /> * All versions before 20.4R3-S10,<br /> * from 21.1R1 through 21.*,<br /> * from 21.2 before 21.2R3-S5,<br /> * from 21.3 before 21.3R3-S5,<br /> * from 21.4 before 21.4R3-S7 (unaffected from 21.4R3-S5, affected from 21.4R3-S6)<br /> * from 22.1 before 22.1R3-S4,<br /> * from 22.2 before 22.2R3-S3,<br /> * from 22.3 before 22.3R3-S1,<br /> * from 22.4 before 22.4R3,<br /> * from 23.2 before 23.2R2.<br /> <br /> <br /> Junos OS Evolved:<br /> <br /> <br /> <br /> * All versions before 20.4R3-S10-EVO,<br /> * from 21.2-EVO before 21.2R3-S7-EVO,<br /> * from 21.3-EVO before 21.3R3-S5-EVO,<br /> * from 21.4-EVO before 21.4R3-S5-EVO,<br /> * from 22.1-EVO before 22.1R3-S4-EVO,<br /> * from 22.2-EVO before 22.2R3-S3-EVO,<br /> * from 22.3-EVO before 22.3R3-S1-EVO,<br /> * from 22.4-EVO before 22.4R3-EVO,<br /> * from 23.2-EVO before 23.2R2-EVO.

FreeRDP es una implementación libre del Protocolo de Escritorio Remoto (RDP), publicado bajo la licencia Apache. Las versiones afectadas están sujetas a un Out-Of-Bounds Read en la función `RleDecompress`. Esta lectura fuera de los límites se produce porque FreeRDP procesa la variable `pbSrcBuffer` sin comprobar si contiene datos de longitud suficiente. Datos insuficientes en la variable `pbSrcBuffer` pueden causar errores o fallos. Este problema se ha solucionado en la versión 3.0.0-beta3. Se recomienda a los usuarios que la actualicen. No se conocen soluciones para este problema.

*** Pendiente de traducción *** FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Affected versions are subject to an Out-Of-Bounds Read in the `general_YUV444ToRGB_8u_P3AC4R_BGRX` function. This issue is likely down to insufficient data for the `pSrc` variable and results in crashes. This issue has been addressed in version 3.0.0-beta3. Users are advised to upgrade. There are no known workarounds for this issue.

*** Pendiente de traducción *** FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Affected versions are subject to an Out-Of-Bounds Write in the `writePixelBGRX` function. This issue is likely down to incorrect calculations of the `nHeight` and `srcStep` variables. This issue has been addressed in version 3.0.0-beta3. Users are advised to upgrade. There are no known workarounds for this issue.

*** Pendiente de traducción *** FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Affected versions of the 3.x beta branch are subject to a Use-After-Free issue in the `avc420_ensure_buffer` and `avc444_ensure_buffer` functions. If the value of `piDstSize[x]` is 0, `ppYUVDstData[x]` will be freed. However, in this case `ppYUVDstData[x]` will not have been updated which leads to a Use-After-Free vulnerability. This issue has been addressed in version 3.0.0-beta3. Users of the 3.x beta releases are advised to upgrade. There are no known workarounds for this vulnerability.

*** Pendiente de traducción *** FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Affected versions are subject to an IntegerOverflow leading to Out-Of-Bound Write Vulnerability in the `gdi_CreateSurface` function. This issue affects FreeRDP based clients only. FreeRDP proxies are not affected as image decoding is not done by a proxy. This issue has been addressed in versions 2.11.0 and 3.0.0-beta3. Users are advised to upgrade. There are no known workarounds for this issue.

*** Pendiente de traducción *** FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Affected versions are subject to an Out-Of-Bounds Read in the `general_LumaToYUV444` function. This Out-Of-Bounds Read occurs because processing is done on the `in` variable without checking if it contains data of sufficient length. Insufficient data for the `in` variable may cause errors or crashes. This issue has been addressed in versions 2.11.0 and 3.0.0-beta3. Users are advised to upgrade. There are no known workarounds for this issue.

*** Pendiente de traducción *** FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Affected versions are subject to an Out-Of-Bounds Write in the `clear_decompress_bands_data` function in which there is no offset validation. Abuse of this vulnerability may lead to an out of bounds write. This issue has been addressed in versions 2.11.0 and 3.0.0-beta3. Users are advised to upgrade. there are no known workarounds for this vulnerability.

*** Pendiente de traducción *** FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Affected versions are subject to an Out-Of-Bounds Write in the `progressive_decompress` function. This issue is likely down to incorrect calculations of the `nXSrc` and `nYSrc` variables. This issue has been addressed in versions 2.11.0 and 3.0.0-beta3. Users are advised to upgrade. there are no known workarounds for this vulnerability.

*** Pendiente de traducción *** FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Affected versions are subject to an Integer-Underflow leading to Out-Of-Bound Read in the `zgfx_decompress_segment` function. In the context of `CopyMemory`, it&amp;#39;s possible to read data beyond the transmitted packet range and likely cause a crash. This issue has been addressed in versions 2.11.0 and 3.0.0-beta3. Users are advised to upgrade. There are no known workarounds for this issue.
