Vulnerabilidad alta en UTT HiPER 1200GW permite desbordamiento de búfer remoto

Se ha identificado un desbordamiento de búfer basado en stack en los modelos UTT HiPER 1200GW versiones hasta 2.5.3-170306, mediante manipulación del parámetro EncryptionMode en la función strcpy del archivo /goform/pptpSrvGlobalConfig. La vulnerabilidad permite ejecución remota de código sin autenticación previa, con CVSS 8.8. El exploit ha sido divulgado públicamente, aumentando el riesgo inmediato para equipos de red altas en LATAM que utilizan este modelo de puerta de enlace.

A vulnerability in the GPT file format parser of ClamAV could allow an unauthenticated, remote attacker to cause a DoS condition or possibly other expanded impacts as a result of&nbsp;memory corruption on an affected device. This vulnerability is due to improper handling of an endian conversion operation, which may result in an out-of-bounds buffer write. An attacker could exploit this vulnerab…

Domoticz's MochadTCP::MatchLine() handler for MOCHAD_RFSEC messages (hardware/MochadTCP.cpp) copies network-received data from the up-to-1028-byte m_mochadbuffer into a fixed 50-byte stack buffer tempRFSECbuf using strcpy() with no length check, across three separate code branches (DS10A/KR10A/MS10A device types).

tinyobjloader-c's tinyobj_parse_and_index_mtl_file() (tinyobj_loader_c.h) reads each line of a .mtl material file into a fixed 4096-byte stack buffer `linebuf` via memcpy(linebuf, p, p_len), guarded only by `assert(p_len < 4095)`. Because assert() compiles to a no-op under -DNDEBUG (standard for release builds), a crafted .mtl file containing a line (e.g. a "newmtl" material name) longer than 4096…

microtar's mtar_write_file_header() and mtar_write_dir_header() functions (src/microtar.c) copy a caller-supplied entry name into the 100-byte `name` field of a stack-allocated mtar_header_t via strcpy(h.name, name), with no check that strlen(name) is less than 100 before the copy. Any application that calls these functions with an externally-influenced filename longer than 99 characters (e.g. whe…

OpenSIPS is a Session Initiation Protocol (SIP) server implementation. In versions 4.0.0 and prior, processing a SIP message with a header name longer than 255 bytes causes a stack buffer overflow when sip_to_json() is called in the routing script. Function sip_to_json() (modules/sipmsgops/sipmsgops.c) copies SIP header names into a fixed 255-byte stack buffer without bounds checking, performing a…
