A flaw was discovered in FasterXML jackson-databind, where it would permit polymorphic deserialization of malicious objects using the ehcache and logback JNDI gadgets when used in conjunction with polymorphic type handling methods such as enableDefaultTyping() or when @JsonTypeInfo is using Id.CLASS or Id.MINIMALCLASS or in any other way which ObjectMapper.readValue might instantiate objects from unsafe sources. An attacker could use this flaw to execute arbitrary code.

Exim 4.92 through 4.92.2 allows remote code execution, a different vulnerability than CVE-2019-15846. There is a heap-based buffer overflow in stringvformat in string.c involving a long EHLO command.

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.

Vulnerable commit https://github.com/python/cpython/commit/d537ab0ff9767ef024f26246899728f0116b1ec3

Upstream patch https://github.com/python/cpython/commit/8d0ef0b5edeae52960c7ed05ae8a12388324f87e

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.

Uptream Patch: https://github.com/python/cpython/pull/12201

A use-after-free in onignewdeluxe() in regext.c in Oniguruma 6.9.2 allows attackers to potentially cause information disclosure, denial of service, or possibly code execution by providing a crafted regular expression. The attacker provides a pair of a regex pattern and a string, with a multi-byte encoding that gets handled by onignewdeluxe(). Oniguruma issues often affect Ruby, as well as common optional libraries for PHP and Rust.

A flaw was found in Perl versions 5.8.0 through 5.28. An Integer overflow leading to buffer overflow in Perlmysetenv function in util.c

Upstream Patch: https://github.com/Perl/perl5/commit/34716e2a6ee2af96078d62b065b7785c001194be

apachemodphp. Multiple issues were addressed by updating to PHP version 7.3.11.

Gnome Pango 1.42 and later is affected by: Buffer Overflow. The impact is: The heap based buffer overflow can be used to get code execution. The component is: function name: pangolog2visgetembeddinglevels, assignment of nchars and the loop condition. The attack vector is: Bug can be used when application pass invalid utf-8 strings to functions like pangoitemize.

A vulnerability was found in LibreOffice prior to 6.2.6. LibreOffice is typically bundled with LibreLogo, a programmable turtle vector graphics script, which can execute arbitrary python commands contained with the document it is launched from. LibreOffice also has a feature where documents can specify that pre-installed scripts can be executed on various document script events such as mouse-over, etc. Protection was added, to address CVE-2019-9848, to block calling LibreLogo from script event handers. However an insufficient url validation vulnerability in LibreOffice allowed malicious to bypass that protection and again trigger calling LibreLogo from script event handlers.

Protection was added, to address CVE-2019-9848, to block calling LibreLogo from document event script handers, e.g. mouse over. However LibreOffice also has a separate feature where documents can specify that pre-installed scripts can be executed on various global script events such as document-open, etc. In the fixed versions, global script event handlers are validated equivalently to document script event handlers.

An issue was discovered in Squid 3.3.9 through 3.5.28 and 4.x through 4.7. When Squid is configured to use Digest authentication, it parses the header Proxy-Authorization. It searches for certain tokens such as domain, uri, and qop. Squid checks if this token's value starts with a quote and ends with one. If so, it performs a memcpy of its length minus 2. Squid never checks whether the value is just a single quote (which would satisfy its requirements), leading to a memcpy of its length minus 1.

Insufficient sanitization of arguments passed to rsync can bypass the restrictions imposed by rssh, a restricted shell that should restrict users to perform only rsync operations, resulting in the execution of arbitrary shell commands.

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.

A malicious server could send a specially crafted packet which could result in an unchecked integer overflow. The value would then be used to allocate memory causing a possible memory write out of bounds error.

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

A server could send a specially crafted SSHMSGCHANNELREQUEST packet with an exit status message and no payload. This would result in an out of bounds memory comparison.
