Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 37 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2023-c08f9dfc16 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)

 - 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.

Solution

Update the affected bzip3 package.
