Uclibc-Ng Project Uclibc-Ng vulnerabilities

CVE-2022-29503 [CRITICAL] CWE-119 CVE-2022-29503: A memory corruption vulnerability exists in the libpthread linuxthreads functionality of uClibC 0.9. 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.

CVE-2022-30295 [MEDIUM] CWE-330 CVE-2022-30295: uClibc-ng through 1.0.40 and uClibc through 0.9.33.2 use predictable DNS transaction IDs that may le 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.

CVE-2021-27419 [CRITICAL] CWE-190 CVE-2021-27419: uClibc-ng versions prior to 1.0.37 are vulnerable to integer wrap-around in functions malloc-simple. 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.

CVE-2021-43523 [CRITICAL] CWE-79 CVE-2021-43523: In uClibc and uClibc-ng before 1.0.39, incorrect handling of special characters in domain names retu 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.).

CVE-2016-2225 [HIGH] CWE-400 CVE-2016-2225: The __read_etc_hosts_r function in libc/inet/resolv.c in uClibc-ng before 1.0.12 allows remote DNS s 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.

CVE-2016-2224 [HIGH] CWE-400 CVE-2016-2224: The __decode_dotted function in libc/inet/resolv.c in uClibc-ng before 1.0.12 allows remote DNS serv 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.

CVE-2016-6264 [HIGH] CVE-2016-6264: Integer signedness error in libc/string/arm/memset.S in uClibc and uClibc-ng before 1.0.16 allows co 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.
