Package: libxcrypt1 Version: 1:2.4-1 Severity: normal I think the crypt_blowfish implementation in libxcrypt 2.4-1 has the sign extension bug detailed in CVE-2011-2483.
Full details of this bug are at: http://seclists.org/oss-sec/2011/q2/632 crypt_blowfish.c in the libxcrypt source package contains the following code, which indicates that it's affected by this bug: for (j = 0; j < 4; j++) { tmp <<= 8; tmp |= *ptr; if (!*ptr) ptr = key; else ptr++; } The problem is in the statement "tmp |= *ptr", where ptr is a plain char. This should be cast to an unsigned char, e.g. tmp |= (unsigned char)*ptr Upgrading to the latest upstream source should fix this bug. -- System Information: Debian Release: wheezy/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: i386 (i686) Kernel: Linux 3.2.0-3-686-pae (SMP w/1 CPU core) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages libxcrypt1 depends on: ii libc6 2.13-33 libxcrypt1 recommends no packages. libxcrypt1 suggests no packages. -- no debconf information -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
