A vulnerability was found in Python 2.7.x through 2.7.16 and 3.x through 3.7.2. An improper Handling of Unicode Encoding (with an incorrect netloc) during NFKC normalization could lead to an Information Disclosure (credentials, cookies, etc. that are cached against a given hostname) in the urllib.parse.urlsplit, urllib.parse.urlparse components. A specially crafted URL could be incorrectly parsed to locate cookies or authentication data and send that information to a different host than when parsed correctly.

Double-free vulnerability in the FTP-kerberos code in cURL 7.52.0 to 7.65.3.

cURL libcurl is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the tftpreceivepacket function. By sending specially-crafted request containing an OACK without the BLKSIZE option, a remote attacker could overflow a buffer and execute arbitrary code on the system.

BZ2decompress in decompress.c in bzip2 through 1.0.6 has an out-of-bounds write when there are many selectors.

A security regression for CVE-2019-9636 was discovered in python's functions urllib.parse.urlsplit and urllib.parse.urlparse, introduced with commit d537ab0ff9767ef024f26246899728f0116b1ec3. No upstream python version is affected by this regression but the vulnerable commit may already have been included downstream as part of the original fix for CVE-2019-9636.

Affected python versions ignore the user/password part before @ in the netloc component of a URL, thus it still allows an attacker to exploit the vulnerability as in CVE-2019-9636. Those functions do not properly handle URLs encoded with Punycode/Internationalizing Domain Names in Applications (IDNA), which may result in a wrong domain name (specifically the netloc component of URL - user@domain:port) being returned by those functions. When an application parses user-supplied URLs to store cookies, authentication credentials, or other kind of information, it is possible for an attacker to provide specially crafted URLs to make the application locate host-related information (e.g. cookies, authentication data) and send them to a different host than where it should, unlike if the URLs had been correctly parsed. The result of an attack may vary based on the application.

postgresql before versions 10.4, 9.6.9 is vulnerable in the adminpack extension, the pgcatalog.pglogfilerotate() function doesn't follow the same ACLs than pgroratelogfile. If the adminpack is added to a database, an attacker able to connect to it could exploit this to force log rotation.

Apache Tomcat could allow a remote attacker to execute arbitrary code on the system, caused by a file read/inclusion vulnerability in the AJP connector. By sending a specially-crafted request, an attacker could exploit this vulnerability to read web application files from a vulnerable server and upload malicious JavaServer Pages (JSP) code within a variety of file types and execute arbitrary code on the system.

Note: This vulnerability is known as Ghostcat.

A flaw was found in dom4j library. By using the default SaxReader() provided by Dom4J, external DTDs and External Entities are allowed, resulting in a possible XXE.

A flaw was discovered in Log4j, where a vulnerable SocketServer class may lead to the deserialization of untrusted data. This flaw allows an attacker to remotely execute arbitrary code when combined with a deserialization gadget.

ircmodechannelupdate in plugins/irc/irc-mode.c in WeeChat through 2.7 allows remote attackers to cause a denial of service (buffer overflow and application crash) or possibly have unspecified other impact via a malformed IRC message 324 (channel mode).

A flaw was found in php before 7.4.2. A global buffer overflow in mbflfiltconvbig5wchar function may lead to corruption of memory data.

A flaw was found in php before 7.4.2. An out of bounds read in phpstriptagsex may lead to denial of service or potentially disclosure of sensitive data.

An issue was discovered in openfortivpn 1.11.0 when used with OpenSSL before 1.0.2. tunnel.c mishandles certificate validation because hostname comparisons do not consider '\0' characters, as demonstrated by a good.example.com\x00evil.example.com attack.

A vulnerability was discovered in the PyYAML library in versions before 5.3.1, where it is susceptible to arbitrary code execution when it processes untrusted YAML files through the fullload method or with the FullLoader loader. Applications that use the library to process untrusted input may be vulnerable to this flaw. An attacker could use this flaw to execute arbitrary code on the system by abusing the python/object/new constructor.

An elevation of privilege vulnerability exists when an attacker establishes a vulnerable Netlogon secure channel connection to a domain controller, using the Netlogon Remote Protocol (MS-NRPC), aka 'Netlogon Elevation of Privilege Vulnerability'.

A user could use shell injections with the Salt API using the SSH Client.

rcubeimage.php in Roundcube Webmail before 1.4.4 allows attackers to execute arbitrary code via shell metacharacters in a configuration setting for imconvertpath or imidentifypath.

A flaw was found in Apache httpd in versions 2.4.32 to 2.4.46. The uwsgi protocol does not serialize more than 16K of HTTP header leading to resource exhaustion and denial of service. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

An issue was discovered in SaltStack Salt before 2019.2.4 and 3000 before 3000.2. The salt-master process ClearFuncs class does not properly validate method calls. This allows a remote user to access some methods without authentication. These methods can be used to retrieve user tokens from the salt master and/or run arbitrary commands on salt minions.

In SaltStack Salt before 2019.2.3, the salt-api NET API with the ssh client enabled is vulnerable to command injection. This allows an unauthenticated attacker with network access to the API endpoint to execute arbitrary code on the salt-api host.

A vulnerability was found in the Linux kernel's generic WiFi ESSID handling implementation. The flaw allows a system to join a wireless network where the ESSID is longer than the maximum length of 32 characters, which can cause the system to crash or execute code.

A flaw in the Linux kernel's WiFi beacon validation code was discovered. The code does not check the length of the variable length elements in the beacon head potentially leading to a buffer overflow. System availability, as well as data confidentiality and integrity, can be impacted by this vulnerability.

A heap-based buffer overflow was discovered in the Linux kernel, all versions 3.x.x and 4.x.x before 4.18.0, in Marvell WiFi chip driver. The flaw could occur when the station attempts a connection negotiation during the handling of the remote devices country settings. This could allow the remote device to cause a denial of service (system crash) or possibly execute arbitrary code.

Fixed bug (Out-of-bounds read in iconv.c:phpiconvmimedecode() due to integer overflow) (CVE-2019-11039).

Fixed bug (heap-buffer-overflow on phpjpgget16) (CVE-2019-11040).

Fixed bug (Heap-buffer-overflow in estrndup via exifprocessIFDTAG) (CVE-2019-11036).

A flaw was found in the Linux kernel. A heap based buffer overflow in mwifiexuapparsetailies function in drivers/net/wireless/marvell/mwifiex/ie.c might lead to memory corruption and possibly other consequences.
