7 security issues in buster high

There are 7 open security issues in buster.

4 important issues:

CVE-2024-33599: nscd: Stack-based buffer overflow in netgroup cache If the Name Service Cache Daemon's (nscd) fixed size cache is exhausted by client requests then a subsequent client request for netgroup data may result in a stack-based buffer overflow. This flaw was introduced in glibc 2.15 when the cache was added to nscd. This vulnerability is only present in the nscd binary.
CVE-2024-33600: nscd: Null pointer crashes after notfound response If the Name Service Cache Daemon's (nscd) cache fails to add a not-found netgroup response to the cache, the client request can result in a null pointer dereference. This flaw was introduced in glibc 2.15 when the cache was added to nscd. This vulnerability is only present in the nscd binary.
CVE-2024-33601: nscd: netgroup cache may terminate daemon on memory allocation failure The Name Service Cache Daemon's (nscd) netgroup cache uses xmalloc or xrealloc and these functions may terminate the process due to a memory allocation failure resulting in a denial of service to the clients. The flaw was introduced in glibc 2.15 when the cache was added to nscd. This vulnerability is only present in the nscd binary.
CVE-2024-33602: nscd: netgroup cache assumes NSS callback uses in-buffer strings The Name Service Cache Daemon's (nscd) netgroup cache can corrupt memory when the NSS callback does not store all strings in the provided buffer. The flaw was introduced in glibc 2.15 when the cache was added to nscd. This vulnerability is only present in the nscd binary.

2 issues postponed or untriaged:

CVE-2023-4806: (needs triaging) A flaw was found in glibc. In an extremely rare situation, the getaddrinfo function may access memory that has been freed, resulting in an application crash. This issue is only exploitable when a NSS module implements only the _nss_*_gethostbyname2_r and _nss_*_getcanonname_r hooks without implementing the _nss_*_gethostbyname3_r hook. The resolved name should return a large number of IPv6 and IPv4, and the call to the getaddrinfo function should have the AF_INET6 address family with AI_CANONNAME, AI_ALL and AI_V4MAPPED as flags.
CVE-2023-4813: (needs triaging) A flaw was found in glibc. In an uncommon situation, the gaih_inet function may use memory that has been freed, resulting in an application crash. This issue is only exploitable when the getaddrinfo function is called and the hosts database in /etc/nsswitch.conf is configured with SUCCESS=continue or SUCCESS=merge.

1 ignored issue:

CVE-2020-1751: An out-of-bounds write vulnerability was found in glibc before 2.31 when handling signal trampolines on PowerPC. Specifically, the backtrace function did not properly check the array bounds when storing the frame address, resulting in a denial of service or potential code execution. The highest threat from this vulnerability is to system availability.
