+Description:
+ According to a BugTraq posting [0], Imran Ghory discovered a time of
+ check time of use (TOCTOU) file mode vulnerability in the bzip2 data
+ compressor [1]. Because bzip2(1) does not safely restore the mode of
+ a file undergoing compression or decompression, a malicious user can
+ potentially change the mode of any file belonging to the user running
+ bzip2(1). The Common Vulnerabilities and Exposures (CVE) project
+ assigned the identifier CAN-2005-0953 [2] to this problem.
+
+ In a unrelated case, a denial of service vulnerability was found
+ in both the bzip2(1) program and its associated library libbz2(3).
+ Specially crafted bzip2 archives lead to an infinite loop in the
+ decompressor which results in an indefinitively large output file.
+ This could be exploited to cause disk space exhaustion. The Common
+ Vulnerabilities and Exposures (CVE) project assigned the identifier
+ CAN-2005-1260 [3] to this problem.
+
+ Please check whether you are affected by running "<prefix>/bin/openpkg
+ rpm -q bzip2". If you have the "bzip2" package installed and its version
+ is affected (see above), we recommend that you immediately upgrade it
+ (see Solution) and any dependent packages as well [4][5].
+
+Solution:
+ Select the updated source RPM appropriate for your OpenPKG release
+ [6][7], fetch it from the OpenPKG FTP service [8][9] or a mirror
+ location, verify its integrity [10], build a corresponding binary
+ RPM from it [4] and update your OpenPKG installation by applying the
+ binary RPM [5]. For the most recent release OpenPKG 2.3, perform the
+ following operations to permanently fix the security problem (for
+ other releases adjust accordingly).
+
+ $ ftp ftp.openpkg.org
+ ftp> bin
+ ftp> cd release/2.3/UPD
+ ftp> get bzip2-1.0.2-2.3.1.src.rpm
+ ftp> bye
+ $ <prefix>/bin/openpkg rpm -v --checksig bzip2-1.0.2-2.3.1.src.rpm
+ $ <prefix>/bin/openpkg rpm --rebuild bzip2-1.0.2-2.3.1.src.rpm
+ $ su -
+ # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/bzip2-1.0.2-2.3.1.*.rpm
+
+ We recommend that you rebuild and reinstall any dependent packages
+ (see above) as well [4][5]. The openpkg build tool can be instrumental
+ in consistently updating and securing the entire OpenPKG instance.
