Joel Esler reports :
CVE-2018-15378 :
Vulnerability in ClamAV’s MEW unpacking feature that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.
Reported by Secunia Research at Flexera.
Fix for a 2-byte buffer over-read bug in ClamAV&s PDF parsing code.
Reported by Alex Gaynor.
CVE-2018-14680 :
An issue was discovered in mspack/chmd.c in libmspack before 0.7alpha. It does not reject blank CHM filenames.
CVE-2018-14681 :
An issue was discovered in kwajd_read_headers in mspack/kwajd.c in libmspack before 0.7alpha. Bad KWAJ file header extensions could cause a one or two byte overwrite.
CVE-2018-14682 :
An issue was discovered in mspack/chmd.c in libmspack before 0.7alpha. There is an off-by-one error in the TOLOWER() macro for CHM decompression. Additionally, 0.100.2 reverted 0.100.1’s patch for CVE-2018-14679, and applied libmspack’s version of the fix in its place.
