xdgmime: heap-based buffer overflow in _xdg_mime_magic_parse_magic_line() in xdgmimemagic.c

A flaw was found in xdgmime. A heap-based buffer overflow can be triggered in xdgmimemagicparsemagicline in the xdgmimemagic.c file on little-endian systems when an attacker-controlled MIME magic file in a user-writable XDG data location e.g., in the $XDGDATAHOME/mime/magic path is parsed by an...

glibc: glibc: Heap buffer overflow via attacker-controlled fopen mode string

A flaw was found in the GNU C Library glibc. This vulnerability could allow an attacker with local access to trigger a heap buffer overflow by manipulating how the fopen function handles certain input. This could lead to minor disruptions in system operations or limited access to sensitive...

389-ds-base: 389-ds-base: heap buffer overflow via SASL wrapped-record length lower-bound underflow in sasl_io_start_packet()

A heap buffer overflow flaw was found in the SASL I/O layer of 389 Directory Server 389-ds-base. In sasliostartpacket, the wrapped-record length read from the wire is validated only against an upper bound. A small wire length 0, 1, or 2 produces an encryptedbuffercount below the already-consumed...
