The remote Fedora 36 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2023-3a821e6e73 advisory.
An issue was discovered in libbzip3.a in bzip3 before 1.3.0. A denial of service (process hang) can occur with a crafted archive because bzip3 does not follow the required procedure for interacting with libsais.
(CVE-2023-29415)
An issue was discovered in libbzip3.a in bzip3 before 1.3.0. A bz3_decode_block out-of-bounds write can occur with a crafted archive because bzip3 does not follow the required procedure for interacting with libsais. (CVE-2023-29416)
DISPUTED An issue was discovered in libbzip3.a in bzip3 1.2.2. There is a bz3_decompress out-of- bounds read in certain situations where buffers passed to bzip3 do not contain enough space to be filled with decompressed data. NOTE: the vendor’s perspective is that the observed behavior can only occur for a contract violation, and thus the report is invalid. (CVE-2023-29417)
An issue was discovered in libbzip3.a in bzip3 before 1.2.3. There is an xwrite out-of-bounds read.
(CVE-2023-29418)
An issue was discovered in libbzip3.a in bzip3 before 1.2.3. There is a bz3_decode_block out-of-bounds read. (CVE-2023-29419)
An issue was discovered in libbzip3.a in bzip3 before 1.2.3. There is a crash caused by an invalid memmove in bz3_decode_block. (CVE-2023-29420)
An issue was discovered in libbzip3.a in bzip3 before 1.2.3. There is an out-of-bounds write in bz3_decode_block. (CVE-2023-29421)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
