  1. MediumCVSS 5.1 EPSS 3.3%

    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.

  2. MediumCVSS 4.3 EPSS 2.6%

    Off-by-one error in the bzinflate function in Bzip2.xs in the Compress-Raw-Bzip2 module before 2.018 for Perl allows context-dependent attackers to cause a denial of service (application hang or crash) via a crafted bzip2 compressed stream that triggers a buffer overflow, a relat...

  3. LowCVSS 3.7 EPSS 0.40%

    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.

  4. LowCVSS 2.1 EPSS 0.39%

    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.

  5. LowCVSS 1.2 EPSS 0.30%

    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 use...

  6. MediumCVSS 5.0 EPSS 1.3%

    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 over...
