krb5: uninitialized pointer use in krb5kdc

KDC in MIT Kerberos 5 (krb5kdc) does not set a global variable for some krb4 message types, which allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via crafted messages that trigger a NULL pointer dereference or double-free.

krb5: possible leak of sensitive data from krb5kdc using krb4 request

The Kerberos 4 support in KDC in MIT Kerberos 5 (krb5kdc) does not properly clear the unused portion of a buffer when generating an error message, which might allow remote attackers to obtain sensitive information, aka "Uninitialized stack values."

scponly: scp restriction bypass

scponly 4.6 and earlier allows remote authenticated users to bypass intended restrictions and execute arbitrary code by invoking scp, as implemented by OpenSSH, with the -F and -o options.

The libdspam7-drv-mysql cron job in Debian GNU/Linux includes the MySQL dspam database password in a command line argument, which might allow local users to read the password by listing the process and its arguments.

xfree86: memory corruption via XInput extension

The XInput extension in X.Org Xserver before 1.4.1 allows context-dependent attackers to execute arbitrary code via requests related to byte swapping and heap corruption within multiple functions, a different vulnerability than CVE-2007-4990.

Race condition in fileserver in OpenAFS 1.3.50 through 1.4.5 and 1.5.0 through 1.5.27 allows remote attackers to cause a denial of service (daemon crash) by simultaneously acquiring and giving back file callbacks, which causes the handler for the GiveUpAllCallBacks RPC to perform linked-list operations without the host_glock lock.

PostgreSQL privilege escalation via dblink

The DBLink module in PostgreSQL 8.2 before 8.2.6, 8.1 before 8.1.11, 8.0 before 8.0.15, 7.4 before 7.4.19, and 7.3 before 7.3.21, when local trust or ident authentication is used, allows remote attackers to gain privileges via unspecified vectors. NOTE: this issue exists because of an incomplete fix for CVE-2007-3278.

unp 1.0.12, and other versions before 1.0.14, does not properly escape file names, which might allow context-dependent attackers to execute arbitrary commands via shell metacharacters in a filename argument. NOTE: this might only be a vulnerability when unp is invoked by a third party product.

SQL injection vulnerability in the Call Detail Record Postgres logging engine (cdr_pgsql) in Asterisk 1.4.x before 1.4.15, 1.2.x before 1.2.25, B.x before B.2.3.4, and C.x before C.1.0-beta6 allows remote authenticated users to execute arbitrary SQL commands via (1) ANI and (2) DNIS arguments.

Issue with core dump owner

The do_coredump function in fs/exec.c in Linux kernel 2.4.x and 2.6.x up to 2.6.24-rc3, and possibly other versions, does not change the UID of a core dump file if it exists before a root process creates a core dump in the same location, which might allow local users to obtain sensitive information.

Send ICMP Nasty Garbage (sing) on Debian GNU/Linux allows local users to append to arbitrary files and gain privileges via the -L (output log file) option. NOTE: this issue is only a vulnerability in limited environments, since sing is not installed setuid, and the administrator would need to override a non-setuid default during installation.

typespeed before 0.6.4 allows remote attackers to cause a denial of service (application crash) via unspecified network behavior that triggers a divide-by-zero error.

libxml2: infinite loop in UTF-8 decoding

The xmlCurrentChar function in libxml2 before 2.6.31 allows context-dependent attackers to cause a denial of service (infinite loop) via XML containing invalid UTF-8 sequences.

Integer overflow in exif.cpp in exiv2 library allows context-dependent attackers to execute arbitrary code via a crafted EXIF file that triggers a heap-based buffer overflow.

vobcopy 0.5.14 allows local users to append data to an arbitrary file, or create an arbitrary new file, via a symlink attack on the (1) /tmp/vobcopy.bla or (2) /tmp/vobcopy_0.5.14.log temporary file.

The NE2000 emulator in QEMU 0.8.2 allows local users to execute arbitrary code by writing Ethernet frames with a size larger than the MTU to the EN0_TCNT register, which triggers a heap-based buffer overflow in the slirp library, aka NE2000 "mtu" heap overflow. NOTE: some sources have used CVE-2007-1321 to refer to this issue as part of "NE2000 network driver and the socket code," but this is the correct identifier for the mtu overflow vulnerability.

QEMU Buffer overflow via crafted "net socket listen" option

Heap-based buffer overflow in QEMU 0.8.2, as used in Xen and possibly other products, allows local users to execute arbitrary code via crafted data in the "net socket listen" option, aka QEMU "net socket" heap overflow. NOTE: some sources have used CVE-2007-1321 to refer to this issue as part of "NE2000 network driver and the socket code," but this is the correct identifier for the individual net socket listen vulnerability.

emacs insufficient safe mode checks

The hack-local-variables function in Emacs before 22.2, when enable-local-variables is set to :safe, does not properly search lists of unsafe or risky variables, which might allow user-assisted attackers to bypass intended restrictions and modify critical program variables via a file containing a Local variables declaration.

iSCSI Enterprise Target (iscsitarget) 0.4.15 uses weak permissions for /etc/ietd.conf, which allows local users to obtain passwords.

dhcpd stack-based buffer overlow

Stack-based buffer overflow in the cons_options function in options.c in dhcpd in OpenBSD 4.0 through 4.2, and some other dhcpd implementations based on ISC dhcp-2, allows remote attackers to execute arbitrary code or cause a denial of service (daemon crash) via a DHCP request specifying a maximum message size smaller than the minimum IP MTU.
