Background
The file package is a utility that determines the type of a file by examining its contents. It is commonly used to identify the file format of unknown files or to verify the integrity of known files. The package includes an ELF parser, which is responsible for parsing and analyzing ELF (Executable and Linkable Format) files. This vulnerability affects the ELF parser in the file package.
Vulnerability Detail
The vulnerability discovered in the file package's ELF parser allows for a denial of service attack. An attacker can exploit this vulnerability by providing a specially crafted ELF file, causing the parser to consume excessive resources and leading to a system crash or unresponsiveness. This vulnerability poses a risk to systems that use the file package to analyze ELF files, potentially impacting their availability and stability.

FAQ
The file package is a utility that determines the type of a file by examining its contents. It is commonly used to identify the file format of unknown files or to verify the integrity of known files.
ELF (Executable and Linkable Format) is a common file format used for executables, object code, shared libraries, and core dumps in Unix-like operating systems.
The vulnerability can be exploited by providing a specially crafted ELF file to the file package's ELF parser. This can be done by an attacker to consume excessive resources and cause a denial of service, leading to system crashes or unresponsiveness.
The stable distribution (wheezy), upcoming stable distribution (jessie), and unstable distribution (sid) are affected by this vulnerability. It is recommended to upgrade to the patched versions mentioned in the 'how_to_fix' section.
The vulnerability can lead to denial of service, impacting the availability and stability of systems that use the file package to analyze ELF files. It can result in system crashes or unresponsiveness, potentially affecting the overall functionality of the affected systems.
