CVE-2026-71267

microtar's mtarwritefileheader and mtarwritedirheader functions src/microtar.c copy a caller-supplied entry name into the 100-byte name field of a stack-allocated mtarheadert via strcpyh.name, name, with no check that strlenname is less than 100 before the copy. Any application that calls these...

CVE-2026-71266

tinyobjloader-c's tinyobjparseandindexmtlfile tinyobjloaderc.h reads each line of a .mtl material file into a fixed 4096-byte stack buffer linebuf via memcpylinebuf, p, plen, guarded only by assertplen 4095. Because assert compiles to a no-op under -DNDEBUG standard for release builds, a crafted...

postgresql: PostgreSQL: Arbitrary code execution vulnerability in 'refint' module

A flaw was found in PostgreSQL. A stack buffer overflow in the 'refint' module allows an unprivileged database user to execute arbitrary code as the operating system user running the database. Additionally, a separate vulnerability exists where, if an application uses a user-controlled column as ...

postgresql: PostgreSQL libpq: Buffer overflow allows server superuser to overwrite client stack memory

A flaw was found in PostgreSQL libpq. A server superuser can exploit a buffer overflow vulnerability in the PQfn function, which is used by client functions such as loexport, loread, lolseek64, and lotell64. This allows the superuser to send an arbitrarily large response, overwriting the client's...

CVE-2026-71266 tinyobjloader-c Stack Buffer Overflow in MTL Material File Line Parsing

tinyobjloader-c's tinyobjparseandindexmtlfile tinyobjloaderc.h reads each line of a .mtl material file into a fixed 4096-byte stack buffer linebuf via memcpylinebuf, p, plen, guarded only by assertplen 4095.

CVE-2026-71266

The CVE-2026-71266 entry concerns tinyobjloader-c. In tinyobj_parse_and_index_mtl_file() (tinyobj_loader_c.h), a line from a .mtl file is copied into a fixed 4096-byte stack buffer linebuf using memcpy(linebuf, p, p_len) with only an assert(p_len

CVE-2026-71267 microtar Stack Buffer Overflow in mtar_write_file_header() and mtar_write_dir_header()

microtar's mtarwritefileheader and mtarwritedirheader functions src/microtar.c copy a caller-supplied entry name into the 100-byte name field of a stack-allocated mtarheadert via strcpyh.name, name, with no check that strlenname is less than 100 before the copy. Any application that calls these...

CVE-2026-71256

nanoMODBUS through v1.23.0 contains an out-of-bounds stack read leading to a wild-pointer write in nmbsreaddeviceidentificationbasic / recvreaddeviceidentificationres in nanomodbus.c. A fixed 3-element stack array order3 = 0,1,2 maps object IDs to buffer indices. The server-supplied objectid fiel...

CVE-2026-61486

UNSUPPORTED WHEN ASSIGNED Stack-based Buffer Overflow vulnerability in Apache Lucy. This issue affects Apache Lucy: all versions. As this project is retired, we do not plan to release a version that fixes this issue. Users are recommended to find an alternative or restrict access to the instance ...

CVE-2026-17544

A flaw was found in PHP. A remote attacker could exploit this vulnerability by providing specially crafted inputs to the bccomp function. This could lead to an out-of-bounds write, resulting in stack and heap corruption. Such memory corruption can enable arbitrary code execution, allowing the...
