1 CVE-2011-4089 264 1 Exec Code 2014-04-16 2014-04-17
4.6
None Local Low Not required Partial Partial Partial
The bzexe command in bzip2 1.0.5 and earlier generates compressed executables that do not properly handle temporary files during extraction, which allows local users to execute arbitrary code by precreating a temporary directory.
2 CVE-2010-0405 189 DoS Exec Code Overflow 2010-09-28 2013-08-21
5.1
None Remote High Not required Partial Partial Partial
Integer overflow in the BZ2_decompress function in decompress.c in bzip2 and libbzip2 before 1.0.6 allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted compressed file.
3 CVE-2008-1372 119 DoS Overflow 2008-03-18 2010-08-21
4.3
None Remote Medium Not required None None Partial
bzlib.c in bzip2 before 1.0.5 allows user-assisted remote attackers to cause a denial of service (crash) via a crafted file that triggers a buffer over-read, as demonstrated by the PROTOS GENOME test suite for Archive Formats.
4 CVE-2005-1260 DoS 2005-05-19 2010-08-21
5.0
None Remote Low Not required None None Partial
bzip2 allows remote attackers to cause a denial of service (hard drive consumption) via a crafted bzip2 file that causes an infinite loop (a.k.a "decompression bomb").
5 CVE-2005-0953 2005-05-02 2010-08-21
3.7
None Local High Not required Partial Partial Partial
Race condition in bzip2 1.0.2 and earlier allows local users to modify permissions of arbitrary files via a hard link attack on a file while it is being decompressed, whose permissions are changed by bzip2 after the decompression is complete.
6 CVE-2002-0761 2002-08-12 2008-09-05
2.1
None Local Low Not required Partial None None
bzip2 before 1.0.2 in FreeBSD 4.5 and earlier, OpenLinux 3.1 and 3.1.1, and possibly systems, uses the permissions of symbolic links instead of the actual files when creating an archive, which could cause the files to be extracted with less restrictive permissions than intended.
7 CVE-2002-0760 2002-08-12 2008-09-05
1.2
None Local High Not required Partial None None
Race condition in bzip2 before 1.0.2 in FreeBSD 4.5 and earlier, OpenLinux 3.1 and 3.1.1, and possibly other operating systems, decompresses files with world-readable permissions before setting the permissions to what is specified in the bzip2 archive, which could allow local users to read the files as they are being decompressed.
8 CVE-2002-0759 2002-08-12 2008-09-05
5.0
None Remote Low Not required None Partial None
bzip2 before 1.0.2 in FreeBSD 4.5 and earlier, OpenLinux 3.1 and 3.1.1, and possibly other operating systems, does not use the O_EXCL flag to create files during decompression and does not warn the user if an existing file would be overwritten, which could allow attackers to overwrite files via a bzip2 archive.
