curl before version 7.61.1 is vulnerable to a buffer overrun in the NTLM authentication code. The internal function Curlntlmcoremknthash multiplies the length of the password by two (SUM) to figure out how large temporary storage area to allocate from the heap. The length value is then subsequently used to iterate over the password and generate output into the allocated storage buffer. On systems with a 32 bit sizet, the math to calculate SUM triggers an integer overflow when the password length exceeds 2GB (2^31 bytes). This integer overflow usually causes a very small buffer to actually get allocated instead of the intended very huge one, making the use of that buffer end up in a heap buffer overflow. (This bug is almost identical to CVE-2017-8816.)
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.
An old inffast.c optimization turns out to not be optimal anymore with modern compilers, and furthermore was not compliant with the C standard, for which decrementing a pointer before its allocated memory is undefined.

Last updated 14 January 2026
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.
Mahara 21.04 before 21.04.7, 21.10 before 21.10.5, 22.04 before 22.04.3, and 22.10 before 22.10.0 potentially allow a PDF export to trigger a remote shell if the site is running on Ubuntu and the flag -dSAFER is not set with Ghostscript.

An exploitable heap out-of-bounds read vulnerability exists in the way CoTURN 4.5.1.1 web server parses POST requests. A specially crafted HTTP POST request can lead to information leaks and other misbehavior. An attacker needs to send an HTTPS request to trigger this vulnerability.
A flaw was discovered in python-pillow does where it does not properly restrict operations within the bounds of a memory buffer when decoding PCX images. An application that uses python-pillow to decode untrusted images may be vulnerable to this flaw, which can allow an attacker to crash the application or potentially execute code on the system.
libImaging/SgiRleDecode.c in Pillow before 6.2.2 has an SGI buffer overflow.
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 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.
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.

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.
An issue was discovered in the Linux kernel before 5.2.3. Out of bounds access exists in the functions ath6klwmipstreamtimeouteventrx and ath6klwmicaceventrx in the file drivers/net/wireless/ath/ath6kl/wmi.c.
A flaw was found in the Linux kernel's Marvell wifi chip driver. A heap overflow in mwifiexprocesstdlsactionframe function in marvell/mwifiex/tdls.c allows remote attackers to cause a denial of service(system crash) or execute arbitrary code. the station receive a tdls setup request or respone frame which the EIDSUPPRATES IE 's length is larger than 32 will cause Heap Overflow.
A heap-based buffer overflow vulnerability was found in the Linux kernel, version kernel-2.6.32, in Marvell WiFi chip driver. A remote attacker could cause a denial of service (system crash) or, possibly execute arbitrary code, when the lbsibssjoinexisting function is called after a STA connects to an AP.
A stack-based buffer overflow was found in the Linux kernel, version kernel-2.6.32, in Marvell WiFi chip driver. An attacker is able to cause a denial of service (system crash) or, possibly execute arbitrary code, when a STA works in IBSS mode (allows connecting stations together without the use of an AP) and connects to another STA.
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.
apachemodphp. Multiple issues were addressed by updating to PHP version 7.3.11.
Fixed bug (Heap-buffer-overflow in estrndup via exifprocessIFDTAG) (CVE-2019-11036).
A flaw was found in Exim versions 4.87 to 4.91 (inclusive). Improper validation of recipient address in delivermessage() function in /src/deliver.c may lead to remote command execution.
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.
