Aggregates CVE and security vulnerability intelligence across all uclibc-ng_project-related products, including CVSS, EPSS, publication dates, and vulnerability intelligence data.
Historical issues mainly involve vendor risk buffer overflow and vendor risk cross-site scripting and related problems; some flaws may lead to vendor impact memory corruption and vendor impact session compromise.
| CVE | Summary | Source | Max CVSS | EPSS % | Published | Updated |
|---|---|---|---|---|---|---|
| CVE-2022-29503 | A memory corruption vulnerability exists in the libpthread linuxthreads functionality of uClibC 0.9.33.2 and uClibC-ng 1.0.40. Thread allocation can lead to memory corruption. An attacker can create threads to trigger this vulnerability. | [email protected] | 9.8 | 0.80% | 2022-09-29 | 2024-11-21 |
| CVE-2022-30295 | uClibc-ng through 1.0.40 and uClibc through 0.9.33.2 use predictable DNS transaction IDs that may lead to DNS cache poisoning. This is related to a reset of a value to 0x2. | [email protected] | 6.5 | 0.33% | 2022-05-06 | 2024-11-21 |
| CVE-2021-27419 | uClibc-ng versions prior to 1.0.37 are vulnerable to integer wrap-around in functions malloc-simple. This improper memory assignment can lead to arbitrary memory allocation, resulting in unexpected behavior such as a crash or a remote code injection/execution. | [email protected] | 7.3 | 2.55% | 2022-05-03 | 2024-11-21 |
| CVE-2021-43523 | In uClibc and uClibc-ng before 1.0.39, incorrect handling of special characters in domain names returned by DNS servers via gethostbyname, getaddrinfo, gethostbyaddr, and getnameinfo can lead to output of wrong hostnames (leading to domain hijacking) or injection into applications (leading to remote code execution, XSS, applications crashes, etc.). In other words, a validation step, which is expected in any stub resolver, does not occur. | [email protected] | 9.6 | 2.89% | 2021-11-10 | 2025-05-05 |
| CVE-2016-2225 | The __read_etc_hosts_r function in libc/inet/resolv.c in uClibc-ng before 1.0.12 allows remote DNS servers to cause a denial of service (infinite loop) via a crafted packet. | [email protected] | 7.5 | 0.83% | 2017-03-24 | 2026-05-13 |
| CVE-2016-2224 | The __decode_dotted function in libc/inet/resolv.c in uClibc-ng before 1.0.12 allows remote DNS servers to cause a denial of service (infinite loop) via vectors involving compressed items in a reply. | [email protected] | 7.5 | 0.94% | 2017-03-24 | 2026-05-13 |
| CVE-2016-6264 | Integer signedness error in libc/string/arm/memset.S in uClibc and uClibc-ng before 1.0.16 allows context-dependent attackers to cause a denial of service (crash) via a negative length value to the memset function. | [email protected] | 7.5 | 2.32% | 2017-01-27 | 2026-05-13 |
