Multiple vulnerabilities have been discovered in faad2, the Freeware Advanced Audio Coder :
CVE-2018-19502
Heap buffer overflow in the function excluded_channels (libfaad/syntax.c). This vulnerability might allow remote attackers to cause denial of service via crafted MPEG AAC data.
CVE-2018-20196
Stack buffer overflow in the function calculate_gain (libfaad/br_hfadj.c). This vulnerability might allow remote attackers to cause denial of service or any unspecified impact via crafted MPEG AAC data.
CVE-2018-20199 CVE-2018-20360
NULL pointer dereference in the function ifilter_bank (libfaad/filtbank.c). This vulnerability might allow remote attackers to cause denial of service via crafted MPEG AAC data.
CVE-2019-6956
Global buffer overflow in the function ps_mix_phase (libfaad/ps_dec.c). This vulnerability might allow remote attackers to cause denial of service or any other unspecified impact via crafted MPEG AAC data.
CVE-2019-15296
Buffer overflow in the function faad_resetbits (libfaad/bits.c). This vulnerability might allow remote attackers to cause denial of service via crafted MPEG AAC data.
For Debian 8 ‘Jessie’, these problems have been fixed in version 2.7-8+deb8u3.
We recommend that you upgrade your faad2 packages.
