GNU libextractor before 1.15 contains a stack-based buffer overflow vulnerability in the process_star_office function that sizes a variable-length stack array from attacker-controlled OLE2 stream data. Attackers can craft malicious StarOffice documents that allocate up to 4 MB on the stack, causing stack overflow and crashing any application extracting metadata from the document.

Calling strfmon and strfmon_l in the GNU C Library version 2.38 to 2.44 can write past the end of the caller-supplied output buffer when a conversion uses right-justified width padding. Exploitation requires an application code path that calls strfmon or strfmon_l with right-justified width padding into a destination buffer that is large enough for the padding to succeed but too small for the int…

Signum Node is a HDD-mined cryptocurrency using an energy efficient and fair Proof-of-Commitment (PoC+) consensus algorithm. Prior to version 3.9.9, an integer overflow in BlockServiceImpl.applyBlock() allowed a miner to receive an arbitrarily inflated block reward by crafting a block with a negative totalFeeCashBackNqt value. The vulnerability was introduced when the SMART_FEES hardfork (block ~1…

Vulnerabilidad de desbordamiento entero en GNU Emacs anterior a 31.0.91 permite fuga de memoria

GNU Emacs antes de la versión 31.0.91 contiene un desbordamiento de entero en el cargador de imágenes PBM/PPM/PGM que permite a un atacante acceder a contenido de memoria heap mediante imágenes manipuladas con dimensiones grandes e índices de color elevados. La vulnerabilidad resulta del uso de aritmética de enteros con signo en la multiplicación de dimensiones e canales de imagen, causando envolvimiento a valores negativos que eluden validaciones de seguridad.

Vulnerabilidad en FileBrowser anterior a 2.63.19 permite creación de cuentas duplicadas en sistemas Windows

FileBrowser versiones anteriores a 2.63.19 no valida correctamente nombres de usuario en sistemas de archivos sin distinción entre mayúsculas y minúsculas (NTFS/Windows). Cuando están habilitados el registro automático y la creación de directorios de usuario, un atacante puede registrar múltiples cuentas con nombres idénticos pero diferente capitalización (ej: Admin y admin), comprometiendo la integridad del control de acceso. Afecta principalmente a servidores Windows y NAS con configuraciones de acceso público en LATAM.

node-tar is a tar archive manipulation library for Node.js. Prior to 7.5.21, node-tar's filesFilter in src/list.ts uses the recursive mapHas helper to walk an archive entry path upward with path.dirname() and no segment cap when tar.t(...) or tar.x(...) receives a non-empty member-selection list.

An out-of-bounds write vulnerability was found in the BFD library's DLX ELF backend (bfd/elf32-dlx.c) in GNU binutils. The dlx_rtype_to_howto() function maps ELF relocation types to internal howto structures but fails to perform adequate bounds checking on attacker-controlled relocation type values (via ELF32_R_TYPE(r_info)) before indexing into the dlx_elf_howto_table[] array.
