Multiple integer overflows in tiffread.c in CamlImages 2.2 might allow remote attackers to execute arbitrary code via TIFF images containing large width and height values that trigger heap-based buffer overflows.

The prep_reprocess_req function in kdc/do_tgs_req.c in the cross-realm referral implementation in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.7 before 1.7.1 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a ticket request.

Unspecified vulnerability in the imagecolortransparent function in PHP before 5.2.11 has unknown impact and attack vectors related to an incorrect "sanity check for the color index."

Unspecified vulnerability in PHP before 5.2.11, and 5.3.x before 5.3.1, has unknown impact and attack vectors related to "missing sanity checks around exif processing."

The php_openssl_apply_verification_policy function in PHP before 5.2.11 does not properly perform certificate validation, which has unknown impact and attack vectors, probably related to an ability to spoof certificates.

The kvm_emulate_hypercall function in arch/x86/kvm/x86.c in KVM in the Linux kernel 2.6.25-rc1, and other versions before 2.6.31, when running on x86 systems, does not prevent access to MMU hypercalls from ring 0, which allows local guest OS users to cause a denial of service (guest kernel crash) and read or write guest kernel memory via unspecified "random addresses."

The g_file_copy function in glib 2.0 sets the permissions of a target file to the permissions of a symbolic link (777), which allows user-assisted local users to modify files of other users, as demonstrated by using Nautilus to modify the permissions of the user home directory.

NFSv4 in the Linux kernel 2.6.18, and possibly other versions, does not properly clean up an inode when an O_EXCL create fails, which causes files to be created with insecure settings such as setuid bits, and possibly allows local users to gain privileges, related to the execution of the do_open_permission function even when a create fails.

Mozilla Firefox 3.6a1, 3.5.3, 3.5.2, and earlier 3.5.x versions, and 3.0.14 and earlier 2.x and 3.x versions, on Linux uses a predictable /tmp pathname for files selected from the Downloads window, which allows local users to replace an arbitrary downloaded file by placing a file in a /tmp location before the download occurs, related to the Download Manager component. NOTE: some of these details are obtained from third party information.

OpenSSL before 0.9.8m does not check for a NULL return value from bn_wexpand function calls in (1) crypto/bn/bn_div.c, (2) crypto/bn/bn_gf2m.c, (3) crypto/ec/ec2_smpl.c, and (4) engines/e_ubsec.c, which has unspecified impact and context-dependent attack vectors.

Unspecified vulnerability in packet.c in the GSM A RR dissector in Wireshark 1.2.0 and 1.2.1 allows remote attackers to cause a denial of service (application crash) via unknown vectors related to "an uninitialized dissector handle," which triggers an assertion failure.

Unspecified vulnerability in the OpcUa (OPC UA) dissector in Wireshark 0.99.6 through 1.0.8 and 1.2.0 through 1.2.1 allows remote attackers to cause a denial of service (memory and CPU consumption) via malformed OPCUA Service CallRequest packets.

The get_random_int function in drivers/char/random.c in the Linux kernel before 2.6.30 produces insufficiently random numbers, which allows attackers to predict the return value, and possibly defeat protection mechanisms based on randomization, via vectors that leverage the function's tendency to "return the same value over and over again for long stretches of time."

Multiple cross-site scripting (XSS) vulnerabilities in Horde Application Framework 3.2 before 3.2.5 and 3.3 before 3.3.5; Groupware 1.1 before 1.1.6 and 1.2 before 1.2.4; and Groupware Webmail Edition 1.1 before 1.1.6 and 1.2 before 1.2.4; allow remote attackers to inject arbitrary web script or HTML via the (1) crafted number preferences that are not properly handled in the preference system (services/prefs.php), as demonstrated by the sidebar_width parameter; or (2) crafted unknown MIME "text parts" that are not properly handled in the MIME viewer library (config/mime_drivers.php).

The form library in Horde Application Framework 3.2 before 3.2.5 and 3.3 before 3.3.5; Groupware 1.1 before 1.1.6 and 1.2 before 1.2.4; and Groupware Webmail Edition 1.1 before 1.1.6 and 1.2 before 1.2.4; reuses temporary filenames during the upload process which allows remote attackers, with privileges to write to the address book, to overwrite arbitrary files and execute PHP code via crafted Horde_Form_Type_image form field elements.

Multiple stack-based buffer overflows in the Sieve plugin in Dovecot 1.0 before 1.0.4 and 1.1 before 1.1.7, as derived from Cyrus libsieve, allow context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted SIEVE script, as demonstrated by forwarding an e-mail message to a large number of recipients, a different vulnerability than CVE-2009-2632.

The core server component in PostgreSQL 8.3 before 8.3.8 and 8.2 before 8.2.14, when using LDAP authentication with anonymous binds, allows remote attackers to bypass authentication via an empty password.

The core server component in PostgreSQL 8.4 before 8.4.1, 8.3 before 8.3.8, 8.2 before 8.2.14, 8.1 before 8.1.18, 8.0 before 8.0.22, and 7.4 before 7.4.26 does not use the appropriate privileges for the (1) RESET ROLE and (2) RESET SESSION AUTHORIZATION operations, which allows remote authenticated users to gain privileges. NOTE: this is due to an incomplete fix for CVE-2007-6600.

The core server component in PostgreSQL 8.4 before 8.4.1, 8.3 before 8.3.8, and 8.2 before 8.2.14 allows remote authenticated users to cause a denial of service (backend shutdown) by "re-LOAD-ing" libraries from a certain plugins directory.

The tc_fill_tclass function in net/sched/sch_api.c in the tc subsystem in the Linux kernel 2.4.x before 2.4.37.6 and 2.6.x before 2.6.31-rc9 does not initialize certain (1) tcm__pad1 and (2) tcm__pad2 structure members, which might allow local users to obtain sensitive information from kernel memory via unspecified vectors.
