Package: aptitude Version: 0.4.11.2-1 Severity: serious Since /var/lock is installed with mode 1777 on debian systems, if /var/lock/aptitude does not yet exist, a normal user can symlink it to an arbitrary location on the filesystem. Aptitude them attempts to open this file with mode O_TRUNC, allowing an ordinary user to truncate an arbitrary file on the filesystem the next time the system administrator opens aptitude.
Aptitude should use O_NOFOLLOW on the open call in question to avoid inadverant truncation. -- Package-specific info: aptitude 0.4.11.2 compiled at Apr 12 2008 04:21:26 Compiler: g++ 4.2.3 (Debian 4.2.3-3) Compiled against: apt version 4.6.0 NCurses version 5.6 libsigc++ version: 2.0.18 Ept support enabled.
