-Subject: [PATCH] CVE-2023-4527: Stack read overflow with large TCP responses
- in no-aaaa mode
-
-Without passing alt_dns_packet_buffer, __res_context_search can only
-store 2048 bytes (what fits into dns_packet_buffer). However,
-the function returns the total packet size, and the subsequent
-DNS parsing code in _nss_dns_gethostbyname4_r reads beyond the end
-of the stack-allocated buffer.
-
-Fixes commit f282cdbe7f436c75864e5640a4 ("resolv: Implement no-aaaa
-stub resolver option") and bug 30842.
-
-(cherry picked from commit bd77dd7e73e3530203be1c52c8a29d08270cb25d)

-Subject: [PATCH] getaddrinfo: Fix use after free in getcanonname
- (CVE-2023-4806)
-
-When an NSS plugin only implements the _gethostbyname2_r and
-_getcanonname_r callbacks, getaddrinfo could use memory that was freed
-during tmpbuf resizing, through h_name in a previous query response.
-
-The backing store for res->at->name when doing a query with
-gethostbyname3_r or gethostbyname2_r is tmpbuf, which is reallocated in
-gethosts during the query. For AF_INET6 lookup with AI_ALL |
-AI_V4MAPPED, gethosts gets called twice, once for a v6 lookup and second
-for a v4 lookup. In this case, if the first call reallocates tmpbuf
-enough number of times, resulting in a malloc, th->h_name (that
-res->at->name refers to) ends up on a heap allocated storage in tmpbuf.
-Now if the second call to gethosts also causes the plugin callback to
-return NSS_STATUS_TRYAGAIN, tmpbuf will get freed, resulting in a UAF
-reference in res->at->name. This then gets dereferenced in the
-getcanonname_r plugin call, resulting in the use after free.
-
-Fix this by copying h_name over and freeing it at the end. This
-resolves BZ #30843, which is assigned CVE-2023-4806.
