gio/gsocks4aproxy.c in GNOME GLib before 2.82.1 has an off-by-one error and resultant buffer overflow because SOCKS4CONNMSGLEN is not sufficient for a trailing '\0' character.

Accessibility. A privacy issue was addressed with improved private data redaction for log entries.

A vulnerability in input validation exists in curl <8.0 during communication using the TELNET protocol may allow an attacker to pass on maliciously crafted user name and "telnet options" during server negotiation. The lack of proper input scrubbing allows an attacker to send content or perform option negotiation without the application's intent. This vulnerability could be exploited if an application allows user input thereby enabling attackers to execute arbitrary code on the system.

A cleartext transmission of sensitive information vulnerability exists in curl <v7.88.0 that could cause HSTS functionality fail when multiple URLs are requested serially. Using its HSTS support, curl can be instructed to use HTTPS instead of usingan insecure clear-text HTTP step even when HTTP is provided in the URL. ThisHSTS mechanism would however surprisingly be ignored by subsequent transferswhen done on the same command line because the state would not be properlycarried on.

A security vulnerability was found in zlib. The flaw triggered a heap-based buffer in inflate in the inflate.c function via a large gzip header extra field. This flaw is only applicable in the call inflateGetHeader.

A vulnerability was found in curl. The issue occurs when doing HTTP(S) transfers, where curl might erroneously use the read callback (CURLOPTREADFUNCTION) to ask for data to send, even when the CURLOPTPOSTFIELDS option has been set if it previously used the same handle to issue a PUT request which used that callback. This flaw may surprise the application and cause it to misbehave and either send off the wrong data or use memory after free or similar in the subsequent POST request.

A vulnerability was found in curl. This issue occurs because when curl saves cookies, alt-svc, and HSTS data to local files, it makes the operation atomic by finalizing the process with a rename from a temporary name to the final target file name. This flaw leads to unpreserved file permissions, either by mistake or by a malicious actor.

In OpenLDAP 2.x before 2.5.12 and 2.6.x before 2.6.2, a SQL injection vulnerability exists in the experimental back-sql backend to slapd, via a SQL statement within an LDAP query. This can occur during an LDAP search operation when the search filter is processed, due to a lack of proper escaping.

Expat (aka libexpat) before 2.4.4 has a signed integer overflow in XMLGetBuffer, for configurations with a nonzero XMLCONTEXTBYTES.

A flaw was found in OpenSSL. The issue in CVE-2022-1292 did not find other places in the crehash script where it possibly passed the file names of certificates being hashed to a command executed through the shell. Some operating systems distribute this script in a manner where it is automatically executed. On these operating systems, this flaw allows an attacker to execute arbitrary commands with the privileges of the script.

The OpenSSL 3.0.4 release introduced a serious bug in the RSA implementation for X8664 CPUs supporting the AVX512IFMA instructions. This issue makes the RSA implementation with 2048 bit private keys incorrect on such machines and memory corruption will happen during the computation. As a consequence of the memory corruption an attacker may be able to trigger a remote code execution on the machine performing the computation. SSL/TLS servers or other servers using 2048 bit RSA private keys running on machines supporting AVX512IFMA instructions of the X8664 architecture are affected by this issue.

A flaw was found in OpenSSL. The crehash script does not properly sanitize shell meta-characters to prevent command injection. Some operating systems distribute this script in a manner where it is automatically executed. This flaw allows an attacker to execute arbitrary commands with the privileges of the script on these operating systems.

The mqnotify function in the GNU C Library (aka glibc) versions 2.32 and 2.33 has a use-after-free. It may use the notification thread attributes object (passed through its struct sigevent parameter) after it has been freed by the caller, leading to a denial of service (application crash) or possibly unspecified other impact.

An issue was discovered in json-c from 20200420 (post 0.14 unreleased code) through 0.15-20200726. A stack-buffer-overflow exists in the auxiliary sample program jsonparse which is located in the function parseit.

An integer wraparound was discovered in glib due to passing a 64 bit sized value to function gmemdup() which accepts a 32 bits number as argument. An attacker may abuse this flaw when an application linked against the glib library uses gbytesnew() function or possibly other functions that use gmemdup() underneath and accept a 64 bits argument as size. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

curl. Multiple issues were addressed by updating to curl version 7.79.1.

A flaw was found in gnutls. A use after free issue in client sending keyshare extension may lead to memory corruption and other consequences.

A vulnerability was found in lz4, where a potential memory corruption due to an integer overflow bug which caused one of the memmove arguments to become negative. Depending on how the library was compiled this will hit an assert() inside the library and dump core, leaving a 4GB core file, or it wil go into libc and crash inside the memmove() function.

A flaw was found in python. A stack-based buffer overflow was discovered in the ctypes module provided within Python. Applications that use ctypes without carefully validating the input passed to it may be vulnerable to this flaw, which would allow an attacker to overflow a buffer on the stack and crash the application. The highest threat from this vulnerability is to system availability.

In SQLite 3.31.1, there is an out of bounds access problem through ALTER TABLE for views that have a nested FROM clause.

In Python 3.8.4, sys.path restrictions specified in a python38.pth file are ignored, allowing code to be loaded from arbitrary locations. The <executable-name>.pth file (e.g., the python.pth file) is not affected.

In SQLite through 3.31.1 the ALTER TABLE implementation has a use-after-free as demonstrated by an ORDER BY clause that belongs to a compound SELECT statement.

lookupName in resolve.c in SQLite 3.30.1 omits bits from the colUsed bitmask in the case of a generated column, which allows attackers to cause a denial of service or possibly have unspecified other impact.

An unspecified error related to the mishandling of NOT NULL in an integritycheck PRAGMA command in pragma.c in SQLite has an unknown impact and attack vector.

GNU glibc is vulnerable to a heap-based buffer overflow, caused by a buffer over-read flaw in the proceednextnode function in posix/regexec.c. By sending a specially-crafted argument using a case-insensitive regular-expression match, a remote attacker could overflow a buffer and execute arbitrary code on the system.

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.
