kernel: mishandling reference counts associated with f2fs_wait_discard_bios calls allowing local attacker to cause denial of service

The f2fs implementation in the Linux kernel before 4.14 mishandles reference counts associated with f2fs_wait_discard_bios calls, which allows local users to cause a denial of service (BUG), as demonstrated by fstrim.

libcdio: NULL pointer dereference in realloc_symlink in rock.c

realloc_symlink in rock.c in GNU libcdio before 1.0.0 allows remote attackers to cause a denial of service (NULL Pointer Dereference) via a crafted iso file.

libcdio: Heap-based buffer over-read in print_iso9660_recurse function in iso-info.c

print_iso9660_recurse in iso-info.c in GNU libcdio before 1.0.0 allows remote attackers to cause a denial of service (heap-based buffer over-read) or possibly have unspecified other impact via a crafted iso file.

jgraphx: XML External Entity (XXE) vulnerability in mxGraphViewImageReader.java:convert()

In mxGraphViewImageReader.java in mxGraph before 3.7.6, the SAXParserFactory instance in convert() is missing flags to prevent XML External Entity (XXE) attacks, as demonstrated by /ServerView.

Leptonica 1.74.4 constructs unintended pathnames (containing duplicated path components) when operating on files in /tmp subdirectories, which might allow local users to bypass intended file restrictions by leveraging access to a directory located deeper within the /tmp directory tree, as demonstrated by /tmp/ANY/PATH/ANY/PATH/input.tif.

An issue was discovered in tools/conversations/view_ajax.php in Concrete5 before 8.3.0. An unauthenticated user can enumerate comments from all blog posts by POSTing requests to /index.php/tools/required/conversations/view_ajax with incremental 'cnvID' integers.

SQL injection vulnerability in users/signup.php in the "signup" component in HamayeshNegar CMS allows a remote attacker to execute arbitrary SQL commands via the "utype" parameter.

kernel: Mishandled extent trees in fs/f2fs/extent_cache.c can allow a local user to cause a denial of service

fs/f2fs/extent_cache.c in the Linux kernel before 4.13 mishandles extent trees, which allows local users to cause a denial of service (BUG) via an application with multiple threads.

smart/calculator/gallerylock/CalculatorActivity.java in the "Photo,Video Locker-Calculator" application through 18 for Android allows attackers to access files via the backdoor 17621762 PIN.

openstack-nova: Swapping encrypted volumes can allow an attacker to corrupt the LUKS header causing a denial of service in the host

An issue was discovered in OpenStack Nova 15.x through 15.1.0 and 16.x through 16.1.1. By detaching and reattaching an encrypted volume, an attacker may access the underlying raw volume and corrupt the LUKS header, resulting in a denial of service attack on the compute host. (The same code error also results in data loss, but that is not a vulnerability because the user loses their own data.) All Nova setups supporting encrypted volumes are affected.

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.

OpenRC opentmpfiles through 0.1.3, when the fs.protected_hardlinks sysctl is turned off, allows local users to obtain ownership of arbitrary files by creating a hard link inside a directory on which "chown -R" will be run.

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.

qpdf: infinite loop due to looping xref tables in QPDF.cc

An issue was discovered in QPDF before 7.0.0. There is an infinite loop due to looping xref tables in QPDF.cc.

qpdf: large heap-based out-of-bounds read in the Pl_Buffer::write function in Pl_Buffer.cc

An issue was discovered in QPDF before 7.0.0. There is a large heap-based out-of-bounds read in the Pl_Buffer::write function in Pl_Buffer.cc. It is caused by an integer overflow in the PNG filter.

qpdf: out-of-bounds read in iterate_rc4 in QPDF_encryption.cc

An issue was discovered in QPDF before 7.0.0. There is a stack-based out-of-bounds read in the function iterate_rc4 in QPDF_encryption.cc.

qpdf: Infinite Loop in QPDFWriter::enqueueObject in libqpdf/QPDFWriter.cc

An issue was discovered in QPDF before 7.0.0. There is an infinite loop in the QPDFWriter::enqueueObject() function in libqpdf/QPDFWriter.cc.

Progress Sitefinity 9.1 uses wrap_access_token as a non-expiring authentication token that remains valid after a password change or a session termination. Also, it is transmitted as a GET parameter. This is fixed in 10.1.

Authenticate/SWT in Progress Sitefinity 9.1 has an open redirect issue in which an authentication token is sent to the redirection target, if the target is specified using a certain %40 syntax. This is fixed in 10.1.
