kernel: Inifinite loop caused by integer overflow in fs/f2fs/data.c:__get_data_block() allows for denial of service

The __get_data_block function in fs/f2fs/data.c in the Linux kernel before 4.11 allows local users to cause a denial of service (integer overflow and loop) via crafted use of the open and fallocate system calls with an FS_IOC_FIEMAP ioctl.

kernel: Race condition in fs/f2fs/node.c:add_free_nid() function allows local users to cause denial of service

The add_free_nid function in fs/f2fs/node.c in the Linux kernel before 4.12 does not properly track an allocated nid, which allows local users to cause a denial of service (race condition) or possibly have unspecified other impact via concurrent threads.

kernel: Null pointer dereference in fs/f2fs/segment.c via mounting fs with noflush_merge option allows local denial of service

fs/f2fs/segment.c in the Linux kernel before 4.13 allows local users to cause a denial of service (NULL pointer dereference and panic) by using a noflush_merge option that triggers a NULL value for a flush_cmd_control data structure.

exempi: Infinite loop in TradQT_Manager::ParseCachedBoxes function in XMPFiles/source/FormatSupport/QuickTime_Support.cpp

An issue was discovered in Exempi before 2.4.4. The TradQT_Manager::ParseCachedBoxes function in XMPFiles/source/FormatSupport/QuickTime_Support.cpp allows remote attackers to cause a denial of service (infinite loop) via crafted XMP data in a .qt file.

exempi: Infinite loop in ASF_Support::ReadHeaderObject function in XMPFiles/source/FormatSupport/ASF_Support.cpp

An issue was discovered in Exempi before 2.4.4. The ASF_Support::ReadHeaderObject function in XMPFiles/source/FormatSupport/ASF_Support.cpp allows remote attackers to cause a denial of service (infinite loop) via a crafted .asf file.

exempi: Use after free via a PDF file containing JPEG data

An issue was discovered in Exempi before 2.4.3. It allows remote attackers to cause a denial of service (invalid memcpy with resultant use-after-free) or possibly have unspecified other impact via a .pdf file containing JPEG data, related to XMPFiles/source/FormatSupport/ReconcileTIFF.cpp, XMPFiles/source/FormatSupport/TIFF_MemoryReader.cpp, and XMPFiles/source/FormatSupport/TIFF_Support.hpp.

exempi: Infinite Loop in Chunk class in XMPFiles/source/FormatSupport/RIFF.cpp

An issue was discovered in Exempi before 2.4.4. Integer overflow in the Chunk class in XMPFiles/source/FormatSupport/RIFF.cpp allows remote attackers to cause a denial of service (infinite loop) via crafted XMP data in a .avi file.

GraphicsMagick: NULL pointer dereference in ReadEnhMetaFile function in coders/emf.c

An issue was discovered in GraphicsMagick 1.3.26. A NULL pointer dereference vulnerability was found in the function ReadEnhMetaFile in coders/emf.c, which allows attackers to cause a denial of service via a crafted file.

GraphicsMagick: NULL pointer dereference in ReadCINEONImage function in coders/cineon.c

An issue was discovered in GraphicsMagick 1.3.26. A NULL pointer dereference vulnerability was found in the function ReadCINEONImage in coders/cineon.c, which allows attackers to cause a denial of service via a crafted file.

GraphicsMagick: allocation failure in ReadTIFFImage function in coders/tiff.c

An issue was discovered in GraphicsMagick 1.3.26. An allocation failure vulnerability was found in the function ReadTIFFImage in coders/tiff.c, which allows attackers to cause a denial of service via a crafted file, because file size is not properly used to restrict scanline, strip, and tile allocations.

GraphicsMagick: Memory allocation failure in coders/png.c:ReadOnePNGImage() allows for denial of service via crafted file

An issue was discovered in GraphicsMagick 1.3.26. An allocation failure vulnerability was found in the function ReadOnePNGImage in coders/png.c, which allows attackers to cause a denial of service via a crafted file that triggers an attempt at a large png_pixels array allocation.

cups: DNS rebinding attacks via incorrect whitelist

A localhost.localdomain whitelist entry in valid_host() in scheduler/client.c in CUPS before 2.2.2 allows remote attackers to execute arbitrary IPP commands by sending POST requests to the CUPS daemon in conjunction with DNS rebinding. The localhost.localdomain name is often resolved via a DNS server (neither the OS nor the web browser is responsible for ensuring that localhost.localdomain is 127.0.0.1).

sox: NULL pointer dereference in startread function in xa.c

In the startread function in xa.c in Sound eXchange (SoX) through 14.4.2, a corrupt header specifying zero channels triggers an infinite loop with a resultant NULL pointer dereference, which may allow a remote attacker to cause a denial-of-service.

In ARM mbed TLS before 2.7.0, there is a bounds-check bypass through an integer overflow in PSK identity parsing in the ssl_parse_client_psk_identity() function in library/ssl_srv.c.

The call parameter of /lib/exe/ajax.php in DokuWiki through 2017-02-19e does not properly encode user input, which leads to a reflected file download vulnerability, and allows remote attackers to run arbitrary programs.

A signature-validation bypass issue was discovered in SimpleSAMLphp through 1.14.16. A SimpleSAMLphp Service Provider using SAML 1.1 will regard as valid any unsigned SAML response containing more than one signed assertion, provided that the signature of at least one of the assertions is valid. Attributes contained in all the assertions received will be merged and the entityID of the first assertion received will be used, allowing an attacker to impersonate any user of any IdP given an assertion signed by the targeted IdP.

The consentAdmin module in SimpleSAMLphp through 1.14.15 is vulnerable to a Cross-Site Scripting attack, allowing an attacker to craft links that could execute arbitrary JavaScript code on the victim's web browser.

systemd: Unsafe handling of hard links allowing privilege escalation

systemd-tmpfiles in systemd before 237 attempts to support ownership/permission changes on hardlinked files even if the fs.protected_hardlinks sysctl is turned off, which allows local users to bypass intended access restrictions via vectors involving a hard link to a file for which the user lacks write access, as demonstrated by changing the ownership of the /etc/passwd file.

In strategy.rb in OmniAuth before 1.3.2, the authenticity_token value is improperly protected because POST (in addition to GET) parameters are stored in the session and become available in the environment of the callback phase.

Qemu: integer overflow in ROUND_UP macro could result in DoS

Integer overflow in the macro ROUND_UP (n, d) in Quick Emulator (Qemu) allows a user to cause a denial of service (Qemu process crash).
