These libraries provide critical APIs including ISO C11, POSIX.1-2008, BSD, OS-specific APIs and more. These APIs include such foundational facilities as open, read, write, malloc, printf, getaddrinfo, dlopen, pthread_create, crypt,  login, exit and more.\r\n\r\nSecurity Fix(es):\n\nCalling wordexp with WRDE_REUSE in conjunction with WRDE_APPEND in the GNU C Library version 2.0 to version 2.42 may cause the interface to return uninitialized memory in the we_wordv member, which on subsequent calls to wordfree may abort the process.(CVE-2025-15281)\n\nCalling getnetbyaddr or getnetbyaddr_r with a configured nsswitch.conf that specifies the library's DNS backend for networks and queries for a zero-valued network in the GNU C Library version 2.0 to version 2.42 can leak stack contents to the configured DNS resolver.(CVE-2026-0915)","affected":[{"package":{"ecosystem":"openEuler:20.03-LTS-SP4","name":"glibc","purl":"pkg:rpm/openEuler/glibc&distro=openEuler-20.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.28-122.oe2003sp4"}]}],"ecosystem_specific":{"aarch64":["glibc-2.28-122.oe2003sp4.aarch64.rpm","glibc-all-langpacks-2.28-122.oe2003sp4.aarch64.rpm","glibc-benchtests-2.28-122.oe2003sp4.aarch64.rpm","glibc-common-2.28-122.oe2003sp4.aarch64.rpm","glibc-compat-2.17-2.28-122.oe2003sp4.aarch64.rpm","glibc-debuginfo-2.28-122.oe2003sp4.aarch64.rpm","glibc-debugsource-2.28-122.oe2003sp4.aarch64.rpm","glibc-debugutils-2.28-122.oe2003sp4.aarch64.rpm","glibc-devel-2.28-122.oe2003sp4.aarch64.rpm","glibc-locale-source-2.28-122.oe2003sp4.aarch64.rpm","glibc-nss-devel-2.28-122.oe2003sp4.aarch64.rpm","libnsl-2.28-122.oe2003sp4.aarch64.rpm","nscd-2.28-122.oe2003sp4.aarch64.rpm","nss_modules-2.28-122.oe2003sp4.aarch64.rpm"],"noarch":["glibc-help-2.28-122.oe2003sp4.noarch.rpm"],"src":["glibc-2.28-122.oe2003sp4.src.rpm"],"x86_64":["glibc-2.28-122.oe2003sp4.x86_64.rpm","glibc-all-langpacks-2.28-122.oe2003sp4.x86_64.rpm","glibc-benchtests-2.28-122.oe2003sp4.x86_64.rpm","glibc-common-2.28-122.oe2003sp4.x86_64.rpm","glibc-compat-2.17-2.28-122.oe2003sp4.x86_64.rpm","glibc-debuginfo-2.28-122.oe2003sp4.x86_64.rpm","glibc-debugsource-2.28-122.oe2003sp4.x86_64.rpm","glibc-debugutils-2.28-122.oe2003sp4.x86_64.rpm","glibc-devel-2.28-122.oe2003sp4.x86_64.rpm","glibc-locale-source-2.28-122.oe2003sp4.x86_64.rpm","glibc-nss-devel-2.28-122.oe2003sp4.x86_64.rpm","libnsl-2.28-122.oe2003sp4.x86_64.rpm","nscd-2.28-122.oe2003sp4.x86_64.rpm","nss_modules-2.28-122.oe2003sp4.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-1266"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-15281"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-0915"}],"database_specific":{"severity":"High"}}
