The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has mesa-libGLw packages installed that are affected by multiple vulnerabilities:

  - An issue was discovered in XListExtensions in ListExt.c in libX11 through 1.6.5. A malicious server can     send a reply in which the first string overflows, causing a variable to be set to NULL that will be freed     later on, leading to DoS (segmentation fault). (CVE-2018-14598)

  - An issue was discovered in libX11 through 1.6.5. The function XListExtensions in ListExt.c is vulnerable     to an off-by-one error caused by malicious server responses, leading to DoS or possibly unspecified other     impact. (CVE-2018-14599)

  - An issue was discovered in libX11 through 1.6.5. The function XListExtensions in ListExt.c interprets a     variable as signed instead of unsigned, resulting in an out-of-bounds write (of up to 128 bytes), leading     to DoS or remote code execution. (CVE-2018-14600)

  - Endless recursion exists in xkbcomp/expr.c in xkbcommon and libxkbcommon before 0.8.1, which could be used     by local attackers to crash xkbcommon users by supplying a crafted keymap file that triggers boolean     negation. (CVE-2018-15853)

  - Unchecked NULL pointer usage in xkbcommon before 0.8.1 could be used by local attackers to crash (NULL     pointer dereference) the xkbcommon parser by supplying a crafted keymap file, because geometry tokens were     desupported incorrectly. (CVE-2018-15854)

  - Unchecked NULL pointer usage in xkbcommon before 0.8.1 could be used by local attackers to crash (NULL     pointer dereference) the xkbcommon parser by supplying a crafted keymap file, because the XkbFile for an     xkb_geometry section was mishandled. (CVE-2018-15855)

  - An infinite loop when reaching EOL unexpectedly in compose/parser.c (aka the keymap parser) in xkbcommon     before 0.8.1 could be used by local attackers to cause a denial of service during parsing of crafted     keymap files. (CVE-2018-15856)

  - An invalid free in ExprAppendMultiKeysymList in xkbcomp/ast-build.c in xkbcommon before 0.8.1 could be     used by local attackers to crash xkbcommon keymap parsers or possibly have unspecified other impact by     supplying a crafted keymap file. (CVE-2018-15857)

  - Unchecked NULL pointer usage when parsing invalid atoms in ExprResolveLhs in xkbcomp/expr.c in xkbcommon     before 0.8.2 could be used by local attackers to crash (NULL pointer dereference) the xkbcommon parser by     supplying a crafted keymap file, because lookup failures are mishandled. (CVE-2018-15859)

  - Unchecked NULL pointer usage in ExprResolveLhs in xkbcomp/expr.c in xkbcommon before 0.8.2 could be used     by local attackers to crash (NULL pointer dereference) the xkbcommon parser by supplying a crafted keymap     file that triggers an xkb_intern_atom failure. (CVE-2018-15861)

  - Unchecked NULL pointer usage in LookupModMask in xkbcomp/expr.c in xkbcommon before 0.8.2 could be used by     local attackers to crash (NULL pointer dereference) the xkbcommon parser by supplying a crafted keymap     file with invalid virtual modifiers. (CVE-2018-15862)

  - Unchecked NULL pointer usage in ResolveStateAndPredicate in xkbcomp/compat.c in xkbcommon before 0.8.2     could be used by local attackers to crash (NULL pointer dereference) the xkbcommon parser by supplying a     crafted keymap file with a no-op modmask expression. (CVE-2018-15863)

  - Unchecked NULL pointer usage in resolve_keysym in xkbcomp/parser.y in xkbcommon before 0.8.2 could be used     by local attackers to crash (NULL pointer dereference) the xkbcommon parser by supplying a crafted keymap     file, because a map access attempt can occur for a map that was never created. (CVE-2018-15864)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
