*** Pendiente de traducción *** The compose-rich-editor library (v1.0.0-rc14) used in HCL Verse for Android's rich text email composition fails to properly validate all HTML input thereby allowing malicious content to be executed in certain situations.

*** Pendiente de traducción *** PhpWeasyPrint is a PHP library allowing PDF generation from a URL or an HTML page. Prior to version 2.6.0, `AbstractGenerator::$temporaryFiles` is a public array, and `removeTemporaryFiles()` — invoked from `__destruct()` and from a registered shutdown function — calls `unlink()` on every entry without verifying that the path is contained within the temporary folder. Any code holding a reference to a generator instance can push an arbitrary path into the array and have it deleted on script shutdown. This mirrors the KnpLabs/snappy issue GHSA-87qc-37cw-84h4. PhpWeasyPrint version 2.6.0 contains a patch for the issue.

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> bpf: Free reuseport cBPF prog after RCU grace period.<br /> <br /> Eulgyu Kim reported the splat below with a repro. [0]<br /> <br /> The repro sets up a UDP reuseport group with a cBPF prog and<br /> replaces it with a new one while another thread is sending<br /> a UDP packet to the group.<br /> <br /> The reuseport prog is freed by sk_reuseport_prog_free().<br /> bpf_prog_put() is called for "e"BPF prog to destruct through<br /> multiple stages while cBPF prog is freed immediately by<br /> bpf_release_orig_filter() and bpf_prog_free().<br /> <br /> If a reuseport prog is detached from the setsockopt() path<br /> (reuseport_attach_prog() or reuseport_detach_prog()),<br /> sk_reuseport_prog_free() is called without waiting for RCU<br /> readers to complete, resulting in various bugs.<br /> <br /> Let&amp;#39;s defer freeing the reuseport cBPF prog after one RCU<br /> grace period.<br /> <br /> Note "e"BPF prog is safe as is unless the fast path starts<br /> to touch fields destroyed in bpf_prog_put_deferred() and<br /> __bpf_prog_put_noref().<br /> <br /> [0]:<br /> BUG: KASAN: vmalloc-out-of-bounds in reuseport_select_sock+0xedc/0x1220 net/core/sock_reuseport.c:596<br /> Read of size 4 at addr ffffc9000051e004 by task slowme/10208<br /> CPU: 6 UID: 1000 PID: 10208 Comm: slowme Not tainted 7.0.0-geb7ac95ff75e #32 PREEMPT(full)<br /> Hardware name: QEMU Ubuntu 24.04 PC v2 (i440FX + PIIX, arch_caps fix, 1996), BIOS 1.16.3-debian-1.16.3-2 04/01/2014<br /> Call Trace:<br /> <br /> dump_stack_lvl+0xe8/0x150 lib/dump_stack.c:120<br /> print_address_description mm/kasan/report.c:378 [inline]<br /> print_report+0xca/0x240 mm/kasan/report.c:482<br /> kasan_report+0x118/0x150 mm/kasan/report.c:595<br /> reuseport_select_sock+0xedc/0x1220 net/core/sock_reuseport.c:596<br /> udp4_lib_lookup2+0x3bc/0x950 net/ipv4/udp.c:495<br /> __udp4_lib_lookup+0x768/0xe20 net/ipv4/udp.c:723<br /> __udp4_lib_lookup_skb+0x297/0x390 net/ipv4/udp.c:752<br /> __udp4_lib_rcv+0x1312/0x2620 net/ipv4/udp.c:2752<br /> ip_protocol_deliver_rcu+0x282/0x440 net/ipv4/ip_input.c:207<br /> ip_local_deliver_finish+0x3bb/0x6f0 net/ipv4/ip_input.c:241<br /> NF_HOOK+0x30c/0x3a0 include/linux/netfilter.h:318<br /> NF_HOOK+0x30c/0x3a0 include/linux/netfilter.h:318<br /> __netif_receive_skb_one_core net/core/dev.c:6181 [inline]<br /> __netif_receive_skb net/core/dev.c:6294 [inline]<br /> process_backlog+0xaa4/0x1960 net/core/dev.c:6645<br /> __napi_poll+0xae/0x340 net/core/dev.c:7709<br /> napi_poll net/core/dev.c:7772 [inline]<br /> net_rx_action+0x5d7/0xf50 net/core/dev.c:7929<br /> handle_softirqs+0x22b/0x870 kernel/softirq.c:622<br /> do_softirq+0x76/0xd0 kernel/softirq.c:523<br /> <br /> <br /> __local_bh_enable_ip+0xf8/0x130 kernel/softirq.c:450<br /> local_bh_enable include/linux/bottom_half.h:33 [inline]<br /> rcu_read_unlock_bh include/linux/rcupdate.h:924 [inline]<br /> __dev_queue_xmit+0x1dd7/0x3710 net/core/dev.c:4890<br /> neigh_output include/net/neighbour.h:556 [inline]<br /> ip_finish_output2+0xca9/0x1070 net/ipv4/ip_output.c:237<br /> NF_HOOK_COND include/linux/netfilter.h:307 [inline]<br /> ip_output+0x29f/0x450 net/ipv4/ip_output.c:438<br /> ip_send_skb+0x45/0xc0 net/ipv4/ip_output.c:1508<br /> udp_send_skb+0xb04/0x1510 net/ipv4/udp.c:1195<br /> udp_sendmsg+0x1a71/0x2350 net/ipv4/udp.c:1485<br /> sock_sendmsg_nosec net/socket.c:727 [inline]<br /> __sock_sendmsg net/socket.c:742 [inline]<br /> __sys_sendto+0x554/0x680 net/socket.c:2206<br /> __do_sys_sendto net/socket.c:2213 [inline]<br /> __se_sys_sendto net/socket.c:2209 [inline]<br /> __x64_sys_sendto+0xde/0x100 net/socket.c:2209<br /> do_syscall_x64 arch/x86/entry/syscall_64.c:63 [inline]<br /> do_syscall_64+0x160/0xf80 arch/x86/entry/syscall_64.c:94<br /> entry_SYSCALL_64_after_hwframe+0x77/0x7f<br /> RIP: 0033:0x415a2d<br /> Code: b3 66 2e 0f 1f 84 00 00 00 00 00 66 90 f3 0f 1e fa 48 89 f8 48 89 f7 48 89 d6 48 89 ca 4d 89 c2 4d 89 c8 4c 8b 4c 24 08 0f 05 3d 01 f0 ff ff 73 01 c3 48 c7 c1 b8 ff ff ff f7 d8 64 89 01 48<br /> RSP: 002b:00007f6bc31e41e8 EFLAGS: 00000212 ORIG_RAX: 000000000000002c<br /> RAX: ffffffffffffffda RBX: 00007f6bc31e4cdc RCX: 0000000000415a2d<br /> RDX: 0000000000000001 RSI: 00007f6bc31e421f RDI: 0000000000000003<br /> RBP: 00007f6bc31e4240 R08: 00007f6bc31e4220 R09: 0000000000000010<br /> R10: 0000000000000000 R11: <br /> ---truncated---

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ip6_vti: set netns_immutable on the fallback device.<br /> <br /> john1988 and Noam Rathaus reported that vti6_init_net() does not set the<br /> netns_immutable flag on the per-netns fallback tunnel device (ip6_vti0).<br /> <br /> Other similar tunnel drivers (like ip6_tunnel, sit, ip6_gre, and ip_tunnel)<br /> correctly set this flag during their fallback device initialization to<br /> prevent them from being moved to another network namespace.

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> RDMA: During rereg_mr ensure that REREG_ACCESS is compatible<br /> <br /> If IB_MR_REREG_ACCESS changes from RO to RW then the umem has to be<br /> re-evaluated to ensure it is properly pinned as RW. Since the umem is<br /> hidden inside each driver&amp;#39;s mr struct add a ib_umem_check_rereg() function<br /> that each driver has to call before processing IB_MR_REREG_ACCESS.<br /> <br /> mlx4 has to retain its duplicate ib_access_writable check because it<br /> implements IB_MR_REREG_ACCESS | IB_MR_REREG_TRANS by changing both items<br /> in place sequentially while the MR is live, so it will continue to not<br /> support this combination.
