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.

The Ubuntu-specific language helper scripts (save-to-pam-env, update-langlist) shipped with accountsservice before 23.13.9-8ubuntu7 treat the user-controlled LANGUAGE entry in ~/.pam_environment as trusted input. The value is interpolated unescaped into a GNU sed replacement expression, allowing an attacker to inject a sed 'e' flag and arbitrary shell commands that execute with the privileges of t…

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. A crafted GNU L or PAX x long-path header with thousands of slash-separated segments reaches this.filt…

A vulnerability was found in SourceCodester Photo Share Website 1.0. This affects an unknown function of the file /social/ajax.php?action=signup. Performing a manipulation of the argument email results in sql injection. Remote exploitation of the attack is possible. The exploit has been made public and could be used.

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. The DLX relocation …

PhpSpreadsheet is a pure PHP library for reading and writing spreadsheet files. In versions 4.0.0 through 5.8.0, 3.3.0 through 3.10.6, 2.2.0 through 2.4.6, 2.0.0 through 2.1.17, and all releases up to and including 1.30.5, the Gnumeric reader reads attacker-supplied .gnumeric files into memory and, when the file starts with gzip magic bytes, calls gzdecode() on the full compressed contents without…
