#buffer_overflow

An issue was discovered in Qt before 5.15.15, 6.x before 6.2.9, and 6.3.x through 6.5.x before 6.5.1. When a SVG file with an image inside it is rendered, a QTextLayout buffer overflow can be triggered.

A vulnerability classified as critical was found in Tenda AC6 US_AC6V1.0BR_V15.03.05.19. Affected by this vulnerability is the function fromDhcpListClient. The manipulation leads to stack-based buffer overflow. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. The identifier VDB-230077 was assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.

Categories: Exploits and vulnerabilities Categories: News Zyxel has released a security advisory about two critical vulnerabilities that could allow an unauthorized, remote attacker to take control of its firewall devices. (Read more...) The post Zyxel patches two critical vulnerabilities appeared first on Malwarebytes Labs.

A heap-based buffer overflow issue was discovered in libjpeg-turbo in h2v2_merged_upsample_internal() function of jdmrgext.c file. The vulnerability can only be exploited with 12-bit data precision for which the range of the sample data type exceeds the valid sample range, hence, an attacker could craft a 12-bit lossless JPEG image that contains out-of-range 12-bit samples. An application attempting to decompress such image using merged upsampling would lead to segmentation fault or buffer overflows, causing an application to crash.

Zyxel has released software updates to address two critical security flaws affecting select firewall and VPN products that could be abused by remote attackers to achieve code execution. Both the flaws – CVE-2023-33009 and CVE-2023-33010 – are buffer overflow vulnerabilities and are rated 9.8 out of 10 on the CVSS scoring system. A brief description of the two issues is below - CVE-2023-33009 -
