curl versions 7.54.1 through 7.60.0 are vulnerable to a heap-based buffer overflow in the Curlsmtpescapeeob() function when uploading data over SMTP and using a reduced read buffer. An attacker could exploit this by convincing a user to use curl to upload data over SMTP with a reduced buffer to cause a crash or corrupt memory.

In postgresql 9.3.x before 9.3.21, 9.4.x before 9.4.16, 9.5.x before 9.5.11, 9.6.x before 9.6.7 and 10.x before 10.2, pgupgrade creates file in current working directory containing the output of pgdumpall -g under umask which was in effect when the user invoked pgupgrade, and not under 0077 which is normally used for other temporary files. This can allow an authenticated attacker to read or modify the one file, which may contain encrypted or unencrypted database passwords. The attack is infeasible if a directory mode blocks the attacker searching the current working directory or if the prevailing umask blocks the attacker opening the file.

A flaw was found in the way Postgresql allowed a user to modify the behavior of a query for other users. An attacker with a user account could use this flaw to execute code with the permissions of superuser in the database.

GnuPG 2.2.4 and 2.2.5 does not enforce a configuration in which key certification requires an offline master Certify key, which results in apparently valid certifications that occurred only with access to a signing subkey.

A flaw was found in the way the Linux kernel handled exceptions delivered after a stack switch operation via Mov SS or Pop SS instructions. During the stack switch operation, processor does not deliver interrupts and exceptions, they are delivered once the first instruction after the stack switch is executed.

An unprivileged system user could use this flaw to crash the system kernel resulting in DoS.

screenresolution-mechanism in screen-resolution-extra 0.17.2 does not properly use the PolicyKit D-Bus API, which allows local users to bypass intended access restrictions by leveraging a race condition via a setuid or pkexec process that is mishandled in a PolicyKitService.checkpermission call.

Incorrect buffer length handling in the ncpreadkernel function in fs/ncpfs/ncplibkernel.c in the Linux kernel through 4.15.11, and in drivers/staging/ncpfs/ncplibkernel.c in the Linux kernel 4.16-rc through 4.16-rc6, could be exploited by malicious NCPFS servers to crash the kernel or execute code.

Dir.open, Dir.new, Dir.entries and Dir.empty? accept the path of the target directory as their parameter. If the parameter contains NUL (\0) bytes, these methods recognize that the path is completed before the NUL bytes. So, if a script accepts an external input as the argument of these methods, the attacker can make the unintentional directory traversal.

Affected versions:

Ruby 2.2 series: 2.2.9 and earlier Ruby 2.3 series: 2.3.6 and earlier Ruby 2.4 series: 2.4.3 and earlier Ruby 2.5 series: 2.5.0 and earlier

In Ruby before 2.2.10, 2.3.x before 2.3.7, 2.4.x before 2.4.4, 2.5.x before 2.5.1, and 2.6.0-preview1, the UNIXServer.open and UNIXSocket.open methods are not checked for null characters. It may be connected to an unintended socket.

If an attacker sends a large request which contains huge HTTP headers, WEBrick try to process it on memory, so the request causes the out-of-memory DoS attack.

Ruby 2.2 series: 2.2.9 and earlier Ruby 2.3 series: 2.3.6 and earlier Ruby 2.4 series: 2.4.3 and earlier Ruby 2.5 series: 2.5.0 and earlier

In Ruby before 2.2.10, 2.3.x before 2.3.7, 2.4.x before 2.4.4, 2.5.x before 2.5.1, and 2.6.0-preview1, an attacker controlling the unpacking format (similar to format string vulnerabilities) can trigger a buffer under-read in the String#unpack method, resulting in a massive and controlled information disclosure.

An issue was discovered in the fdlockedioctl function in drivers/block/floppy.c in the Linux kernel through 4.15.7. The floppy driver will copy a kernel pointer to user memory in response to the FDGETPRM ioctl. An attacker can send the FDGETPRM ioctl and use the obtained kernel pointer to discover the location of kernel code and data and bypass kernel security protections such as KASLR.

An issue was discovered in Exempi through 2.4.4. A certain case of a 0xffffffff length is mishandled in XMPFiles/source/FormatSupport/PSIRFileWriter.cpp, leading to a heap-based buffer over-read in the PSDMetaHandler::CacheFileData() function.

An issue was discovered in Exempi through 2.4.4. XMPFiles/source/FileHandlers/TIFFHandler.cpp mishandles a case of a zero length, leading to a heap-based buffer over-read in the MD5Update() function in third-party/zuid/interfaces/MD5.cpp.

An issue was discovered in Exempi through 2.4.4. XMPFiles/source/FormatSupport/WEBPSupport.cpp does not check whether a bitstream has a NULL value, leading to a NULL pointer dereference in the WEBP::VP8XChunk class.

An issue was discovered in Exempi through 2.4.4. There is a stack-based buffer over-read in the PostScriptMetaHandler::ParsePSFile() function in XMPFiles/source/FileHandlers/PostScriptHandler.cpp.

An issue was discovered in ZZIPlib 0.13.68. There is a bus error caused by the zzipparserootdirectory function of zip.c. Attackers could leverage this vulnerability to cause a denial of service via a crafted zip file.

An issue was discovered in ZZIPlib 0.13.68. An invalid memory address dereference was discovered in zzipdiskfread in mmapped.c. The vulnerability causes an application crash, which leads to denial of service.

A flaw was found in zsh prior 5.4.2. There is a crash when copying empty hash table with typeset -p.

In subst.c in zsh through 5.4.2, there is a NULL pointer dereference when using ${(PA)...} on an empty array result.

An issue was discovered in Django 2.0 before 2.0.3, 1.11 before 1.11.11, and 1.8 before 1.8.19. If django.utils.text.Truncator's chars() and words() methods were passed the html=True argument, they were extremely slow to evaluate certain inputs due to a catastrophic backtracking vulnerability in a regular expression. The chars() and words() methods are used to implement the truncatecharshtml and truncatewordshtml template filters, which were thus vulnerable.

An issue was discovered in Django 2.0 before 2.0.3, 1.11 before 1.11.11, and 1.8 before 1.8.19. The django.utils.html.urlize() function was extremely slow to evaluate certain inputs due to catastrophic backtracking vulnerabilities in two regular expressions (only one regular expression for Django 1.8.x). The urlize() function is used to implement the urlize and urlizetrunc template filters, which were thus vulnerable.
