It was discovered that the RMI (Java Remote Method Invocation) server implementation in the JMX (Java Management Extensions) component of OpenJDK did not restrict which classes can be deserialized when deserializing authentication credentials. A remote unauthenticated attacker able to connect to a JMX port could possibly use this flaw trigger deserialization flaws.

A stack overflow vulnerability was found in nan functions that could cause applications which process long strings with the nan function to crash or, potentially, execute arbitrary code.

Google Chromium V8 Engine contains an out-of-bounds read vulnerability that allows a remote attacker to cause a denial of service or possibly have another unspecified impact via crafted JavaScript code. This vulnerability could affect multiple web browsers that utilize Chromium, including, but not limited to, Google Chrome, Microsoft Edge, and Opera.

Buffer overflow in the maingetappheader function in xdelta3-main.h in xdelta3 before 3.0.9 allows remote attackers to execute arbitrary code via a crafted input file.

Multiple unspecified vulnerabilities in Google Chrome before 51.0.2704.63 allow attackers to cause a denial of service or possibly have other impact via unknown vectors.

named in ISC BIND 9.x before 9.9.8-P4 and 9.10.x before 9.10.3-P4 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a crafted signature record for a DNAME record, related to db.c and resolver.c.

A vulnerability was found in ImageMagick. Insufficient filtering for filename passed to delegate's command allows remote code execution during conversion of several file formats.

ImageMagick allows to process files with external libraries. This feature is called 'delegate'. It is implemented as a system() with command string ('command') from the config file delegates.xml with actual value for different params (input/output filenames etc). Due to insufficient %M param filtering it is possible to conduct shell command injection. One of the default delegate's command is used to handle https requests:

"wget" -q -O "%o" "https:%M"

where %M is the actual link from the input. It is possible to pass the value like https://example.com"|ls "-la and execute unexpected 'ls -la'. (wget or curl should be installed).

A vulnerability was found in the libxml2 library. A heap-based buffer overread could happen in xmlNextChar.

apache. Multiple issues existed in Apache. These were addressed by updating Apache to version 2.4.25.

An application that includes BeanShell on the classpath may be vulnerable if another part of the application uses Java serialization or XStream to deserialize data from an untrusted source.

A vulnerable application could be exploited for remote code execution, including executing arbitrary shell commands.

Apache Tomcat uses a package renamed copy of Apache Commons FileUpload to implement the file upload requirements of the Servlet specification. A denial of service vulnerability was identified in Commons FileUpload that occurred when the length of the multipart boundary was just below the size of the buffer (4096 bytes) used to read the uploaded file. This caused the file upload process to take several orders of magnitude longer than if the boundary was the typical tens of bytes long.

If PAM is configured to read user-specified environment variables and UseLogin=yes in sshdconfig, then a hostile local user may attack /bin/login via LDPRELOAD or similar environment variables set via PAM.

It was reported that drivers/infiniband stack uses write() as a replacement for bi-directional ioctl(), which is not safe. There are ways to trigger write calls that result in the return structure that is normally written to user space being shunted off to user specified kernel memory instead.

A local unprivileged user on a system with rdmaucm module loaded could use this flaw to escalate their privileges.

Any Python module in sys.path can be imported if the command line of the process triggering the coredump is Python and the first argument is -m in Apport before 2.19.2 function pythonmodulepath.

The LoadSBitPng function in sfnt/pngshim.c in FreeType before 2.5.4 does not restrict the rows and pitch values of PNG data, which allows remote attackers to cause a denial of service (integer overflow and heap-based buffer overflow) or possibly have unspecified other impact by embedding a PNG file in a .ttf font file.

Directory traversal vulnerability in KArchive before 5.24, as used in KDE Frameworks, allows remote attackers to write to arbitrary files via a ../ (dot dot slash) in a filename in an archive file, related to KNewsstuff downloads.

Info-ZIP UnZip 6.0 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) or possibly execute arbitrary code via a crafted password-protected ZIP archive possibly related to an Extra-Field size value.

named in ISC BIND 9.x before 9.9.8-P4 and 9.10.x before 9.10.3-P4 does not properly handle DNAME records when parsing fetch reply messages, which allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a malformed packet to the rndc (aka control channel) interface, related to alist.c and sexpr.c.

Integer overflow in the gdkcairosetsourcepixbuf function in gdk/gdkcairo.c in GTK+ before 3.9.8, as used in eom, gnome-photos, eog, gambas3, thunar, pinpoint, and possibly other applications, allows remote attackers to cause a denial of service (crash) via a large image file, which triggers a large memory allocation.

The ssldoconnect function in common/server.c in HexChat before 2.10.2, XChat, and XChat-GNOME does not verify that the server hostname matches a domain name in the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.

Expat, when used in a parser that has not called XMLSetHashSalt or passed it a seed of 0, makes it easier for context-dependent attackers to defeat cryptographic protection mechanisms via vectors involving use of the srand function.

A flaw was found in the way TLS 1.2 could use the MD5 hash function for signing ServerKeyExchange and Client Authentication packets during a TLS handshake. A man-in-the-middle attacker able to force a TLS connection to use the MD5 hash function could use this flaw to conduct collision attacks to impersonate a TLS server or an authenticated TLS client.

The EPHEMERAL coder in ImageMagick before 6.9.3-10 and 7.x before 7.0.1-1 allows remote attackers to delete arbitrary files via a crafted image.

The compressbidderinit function in archivereadsupportfiltercompress.c in libarchive before 3.2.0 allows remote attackers to cause a denial of service (crash) via a crafted tar file, which triggers an invalid left shift.

The (1) HTTP and (2) FTP coders in ImageMagick before 6.9.3-10 and 7.x before 7.0.1-1 allow remote attackers to conduct server-side request forgery (SSRF) attacks via a crafted image.

A flaw in certain programs that handle UDP traffic was discovered and assigned the name CVE-1999-0103 (that CVE specifically mentions echo and chargen as vulnerable). In 2002, a Nessus plugin was included [1] that reference this CVE name, but was for the kpasswd service. Until recently, this issue had not been reported upstream. This issue has since been reported upstream [2] and is now fixed [3].

If a malicious remote user were to spoof their IP address to that of another server running kadmind with the password change port (kpasswd, port 464), or to the target server's IP address itself), kpasswd will pass UDP packets to the spoofed address and reply each time. This can be used to consume bandwidth and CPU on the affected servers running kadmind.

This should be fixed in the for krb5-1.11.3 release.

sosreport in Red Hat sos 1.7 and earlier on Red Hat Enterprise Linux (RHEL) 5 produces an archive with an fstab file potentially containing cleartext passwords, and lacks a warning about reviewing this archive to detect included passwords, which might allow remote attackers to obtain sensitive information by leveraging access to a technical-support data stream.

Possible buffer read overflow was fixed upstream [1]. This was also reported against PHP: https://bugs.php.net/bug.php?id=68601 (bug is private, fixed in PHP 5.6.5)

The psffwrite function in fileio.c in libsndfile allows attackers to cause a denial of service (divide-by-zero error and application crash) via unspecified vectors related to the headindex variable.
