CVE-2022-29503 [CRITICAL] CVE-2022-29503: uclibc - A memory corruption vulnerability exists in the libpthread linuxthreads function... 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. Scope: local bookworm: open bullseye: open forky: open sid: open trixie: open

CVE-2022-30295 [MEDIUM] CVE-2022-30295: uclibc - uClibc-ng through 1.0.40 and uClibc through 0.9.33.2 use predictable DNS transac... 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. Scope: local bookworm: open bullseye: open forky: open sid: open trixie: open

CVE-2021-27419 [HIGH] CVE-2021-27419: uclibc - uClibc-ng versions prior to 1.0.37 are vulnerable to integer wrap-around in func... 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. Scope: local bookworm: open bullseye: open forky: resolved (fixed in 1.0.54-1) sid: resolved (fixed in 1.0.5

CVE-2021-43523 [CRITICAL] CVE-2021-43523: uclibc - In uClibc and uClibc-ng before 1.0.39, incorrect handling of special characters ... 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.).
