NewStart CGSL MAIN 4.06 : tar Multiple Vulnerabilities (NS-SA-2019-0089)
High Nessus Plugin ID 127307
SynopsisThe remote machine is affected by multiple vulnerabilities.
DescriptionThe remote NewStart CGSL host, running version MAIN 4.06, has tar packages installed that are affected by multiple vulnerabilities:
- Buffer overflow in tar 1.14 through 1.15.90 allows user- assisted attackers to cause a denial of service (application crash) and possibly execute code via unspecified vectors involving PAX extended headers.
- GNU tar 1.16 and 1.15.1, and possibly other versions, allows user-assisted attackers to overwrite arbitrary files via a tar file that contains a GNUTYPE_NAMES record with a symbolic link, which is not properly handled by the extract_archive function in extract.c and extract_mangle function in mangle.c, a variant of CVE-2002-1216. (CVE-2006-6097)
- Directory traversal vulnerability in the contains_dot_dot function in src/names.c in GNU tar allows user-assisted remote attackers to overwrite arbitrary files via certain //.. (slash slash dot dot) sequences in directory symlinks in a TAR archive.
- Buffer overflow in the safer_name_suffix function in GNU tar has unspecified attack vectors and impact, resulting in a crashing stack. (CVE-2007-4476)
- Heap-based buffer overflow in the rmt_read__ function in lib/rtapelib.c in the rmt client functionality in GNU tar before 1.23 and GNU cpio before 2.11 allows remote rmt servers to cause a denial of service (memory corruption) or possibly execute arbitrary code by sending more data than was requested, related to archive filenames that contain a : (colon) character.
- Directory traversal vulnerability in the safer_name_suffix function in GNU tar 1.14 through 1.29 might allow remote attackers to bypass an intended protection mechanism and write to arbitrary files via vectors related to improper sanitization of the file_name parameter, aka POINTYFEATHER. (CVE-2016-6321)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
SolutionUpgrade the vulnerable CGSL tar packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
