CVE-2015-3315

Automatic Bug Reporting Tool (ABRT) permite a usuarios locales leer, cambiar la propiedad o realizar otras acciones no especificada en archivos arbitrarios mediante symlink attack en (1) / var / tmp / abrt / * / maps, (2) / tmp /jvm-*/hs_error.log, (3) / proc / * / exe, (4) / etc / os-release en un chroot, o (5) un directorio raíz no especificado relacionado con librpm.

It was found that ABRT was vulnerable to multiple race condition and symbolic link flaws. A local attacker could use either of these flaws to potentially escalate their privileges on the system.

ABRT is a tool to help users to detect defects in applications and to create a bug report with all the information needed by a maintainer to fix it. It uses a plug-in system to extend its functionality. It was found that ABRT was vulnerable to multiple race condition and symbolic link flaws. A local attacker could use these flaws to potentially escalate their privileges on the system. It was discovered that the kernel-invoked coredump processor provided by ABRT wrote core dumps to files owned by other system users. This could result in information disclosure if an application crashed while its current directory was a directory writable to by other users.
