The Linux kernel before 2.6.25.10 does not properly perform tty operations, which allows local users to cause a denial of service (system crash) or possibly gain privileges via vectors involving NULL pointer dereference of function pointers in (1) hamradio/6pack.c, (2) hamradio/mkiss.c, (3) irda/irtty-sir.c, (4) ppp_async.c, (5) ppp_synctty.c, (6) slip.c, (7) wan/x25_asy.c, and (8) wireless/strip.c in drivers/net/.
CWE-476
CVE-2008-1672
OpenSSL 0.9.8f and 0.9.8g allows remote attackers to cause a denial of service (crash) via a TLS handshake that omits the Server Key Exchange message and uses “particular cipher suites,” which triggers a NULL pointer dereference.
CVE-2007-1327
The SILC_SERVER_CMD_FUNC function in apps/silcd/command.c in silc-server 1.0.2 allows remote attackers to cause a denial of service (NULL dereference and daemon crash) via a request without a cipher algorithm and an invalid HMAC algorithm.
CVE-2007-0887
axigen 1.2.6 through 2.0.0b1 does not properly parse login credentials, which allows remote attackers to cause a denial of service (NULL dereference and application crash) via a base64-encoded “*x00” sequence on the imap port (143/tcp).
CVE-2007-0039
The Exchange Collaboration Data Objects (EXCDO) functionality in Microsoft Exchange Server 2000 SP3, 2003 SP1 and SP2, and 2007 allows remote attackers to cause a denial of service (crash) via an Internet Calendar (iCal) file containing multiple X-MICROSOFT-CDO-MODPROPS (MODPROPS) properties in which the second MODPROPS is longer than the first, which triggers a NULL pointer dereference and an unhandled exception.
CVE-2018-9190
A null pointer dereference vulnerability in Fortinet FortiClientWindows 6.0.2 and earlier allows attacker to cause a denial of service via the NDIS miniport driver.
