+Description:
+ The vulnerabilities described by this text affect the openpkg
+ bootstrap package's gzip and bzip2 embedded software. Similar
+ advisories [0][1] describe the same vulnerabilities, although
+ in context of the particular vendor software.
+
+ According to a Debian bug report [2], Ulf Harnhammar discovered
+ an input validation error in the gzip data compressor [3]. Because
+ gzip(1) fails to properly validate file paths during decompression
+ with the "-N" argument, a remote attacker using a malicious archive
+ could corrupt arbitrary files with the privileges of the user that
+ is running gzip(1). The Common Vulnerabilities and Exposures (CVE)
+ project assigned the identifier CAN-2005-1228 [4] to this problem.
+
+ According to a BugTraq posting [5], Imran Ghory discovered a time of
+ check time of use (TOCTOU) file mode vulnerability in the bzip2 data
+ compressor [6]. 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 [7] to this problem.
+
+ In a unrelated bzip2 problem, 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 [8] to this problem.
+
+ Please check whether you are affected by running "<prefix>/bin/openpkg
+ rpm -q openpkg". If the openpkg package version is affected (see above),
+ we recommend that you immediately upgrade it (see Solution) [9][10].
+
+Solution:
+ Select the updated source RPM appropriate for your OpenPKG release
+ [11][12], fetch it from the OpenPKG FTP service [13][14] or a mirror
+ location, verify its integrity [15], build a corresponding binary
+ RPM from it [9] and update your OpenPKG installation by applying the
+ binary RPM [10]. 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 openpkg-2.3.2-2.3.2.src.rpm
+ ftp> bye
+ $ <prefix>/bin/openpkg rpm -v --checksig openpkg-2.3.2-2.3.2.src.rpm
+ $ <prefix>/bin/openpkg rpm --rebuild openpkg-2.3.2-2.3.2.src.rpm
+ $ su -
+ # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/openpkg-2.3.2-2.3.2.*.rpm
