Description
This security bulletin contains information about 4 vulnerabilities.
1) Buffer overflow (CVE-ID: CVE-2024-25580)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when reading KTX images. A remote attacker can pass a specially crafted image to the application, trigger memory corruption and perform a denial of service (DoS) attack.
2) Input validation error (CVE-ID: CVE-2024-33861)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to bypass implemented security restrictions.
The vulnerability exists due to an unspecified error. A local user can bypass implemented security restrictions.
3) Time-of-check Time-of-use (TOCTOU) Race Condition (CVE-ID: CVE-2024-39936)
CWE-ID: CWE-367 - Time-of-check Time-of-use (TOCTOU) Race Condition
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to a race condition in HTTP2 support when establishing an encrypted connection. A remote attacker can potentially force the application to send data before the encrypted() signal, leading to potential information disclosure.
4) Heap-based buffer overflow (CVE-ID: CVE-2025-3512)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in QTextMarkdownImporter when processing an incorrectly formatted markdown file. A remote attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
