CVSS v3.1 |
| ytnef through 2.1.2 contains a heap out-of-bounds read vulnerability in DecompressRTF() in lib/ytnef.c that never validates uncompressedSize for uncompressed RTF streams. Attackers can supply a crafted winmail.dat TNEF attachment with a malicious PT_BINARY MAPI property to crash ytnefprint or libytnef callers and leak adjacent heap memory. |
| libregf through 20260526 contains a heap out-of-bounds read in libregf_value_item_read_value_data() because it bounds value data size without subtracting the 4-byte old-format cell offset. Attackers can supply a crafted version 1.0/1.1 REGF hive with a value data cell ending its hive bin to leak adjacent heap bytes or crash parsers like regfexport and plaso. |
| libfwsi through 20260522 contains a heap out-of-bounds read vulnerability in libfwsi_mtp_volume_values_read_data() that allows attackers to read past buffer bounds via crafted MTP volume shell items. Attackers can embed a 10 to 53 byte shell item with item data size of 44 or more in a .lnk file, jump list or shell bag to crash consuming processes. |
| OpenSlide through 4.0.1 contains a heap out-of-bounds read vulnerability in the MIRAX reader that allows attackers to read past the slide_positions array via crafted Slidedat.ini values. Attackers can supply a MIRAX slide whose CameraImageDivisionsPerSide does not evenly divide the image counts, crashing applications that open it and corrupting tile geometry. |
| AdPlug through 2.4 contains an out-of-bounds read vulnerability in src/xsm.cpp that allows attackers to read before note_table by supplying a negative note index. Attackers can craft an XSM file with the ofTAZ! signature and a song byte of 0x80 or higher, causing a global-buffer-overflow read during playback that may crash affected applications. |
| A security vulnerability has been detected in Tenda AC19 16.03.10.07. The impacted element is the function formSetFirewallCfg of the file /goform/SetFirewallCfg of the component httpd Web Management Service. Such manipulation of the argument firewallEn leads to stack-based buffer overflow. The attack may be launched remotely. The exploit has been disclosed publicly and may be used. |
| FreeRDP before 3.32.1 contains a heap out-of-bounds read vulnerability in the Android client that allows malicious RDP servers to read beyond surface buffers by supplying unvalidated mappedWidth and mappedHeight values. Attackers can send a crafted RDPGFX_MAP_SURFACE_TO_WINDOW_PDU with oversized dimensions, causing android_UpdateWindowFromSurface to copy heap memory beyond the allocation, leading to crashes or memory disclosure. |
| FreeRDP before 3.32.1 contains a heap-based out-of-bounds read in WinPR's clipboard PNG-to-CF_DIB synthesis because winpr_read_png_from_buffer() allocates a bit-packed buffer for PNGs with bit depth below 8, while winpr_bitmap_write_buffer() copies rows assuming one byte per pixel. A malicious RDP server can send a crafted low-bit-depth PNG clipboard payload that, when pasted by the victim, discloses megabytes of heap memory. |
| FreeRDP before 3.32.1 on Windows contains a heap out-of-bounds read in client_cli_present_gateway_message that passes a byte count as wide-character printf precision. A malicious RD Gateway can send pre-authentication consent or service messages, causing the client to read twice the buffer size, leaking heap memory or crashing. |
| Vyper before 0.2.6 contains a call stack corruption vulnerability that causes incorrect function outputs when complex types with non-base members are passed as arguments. Contracts passing multi-dimensional arrays or structs to internal or external functions receive corrupted values because the compiler assumed each subtype size is 32. |
| A stack-based buffer overflow vulnerability could allow a remote authenticated attacker to achieve arbitrary code execution. |
| When authenticating to a POP3 or SMTP server using NTLM, Thunderbird did not check whether the server's challenge was valid base64. A malicious server could send a challenge that caused Thunderbird to include uninitialized heap memory in its NTLM response, disclosing that memory to the server. A challenge consisting only of base64 padding also caused an out-of-bounds read, crashing Thunderbird. This affected accounts configured to use NTLM or GSSAPI authentication. The uninitialized memory disclosure only affected NTLM. This vulnerability was fixed in Thunderbird 158.0.1 and Thunderbird 153.5.1. |
| PolymorphicTypeValidator bypass via generic type arguments and array element types in jackson-databind allows arbitrary class instantiation (incomplete fix for CVE-2026-54512) [CVE-2026-110879] |
| Out-of-bounds read in SQL Server allows an authorized attacker to disclose information over a network. |
| A stack-based buffer overflow vulnerability in the login functionality could allow an attacker to achieve code execution. |
| An integer underflow was addressed with improved input validation. This issue is fixed in macOS Golden Gate 27, macOS Sequoia 15.8, macOS Tahoe 26.7. An attacker with control of a network file server may be able to cause unexpected system termination. |
| An integer overflow vulnerability in the license manager service could allow an unauthenticated attacker to crash the service. |
| Heap-based buffer overflow in Microsoft Office Excel allows an unauthorized attacker to execute code over a network. |
| In the Linux kernel, the following vulnerability has been resolved:
tipc: reject invalid and unexpected GRP_ACK_MSG to prevent bc_ackers underflow
Commit 48a5fe38772b ("tipc: fix bc_ackers underflow on duplicate
GRP_ACK_MSG") rejected duplicate/stale ACKs in tipc_group_proto_rcv()
by returning early when less_eq(acked, m->bc_acked).
However, that check remains incomplete in two ways:
1. When grp->bc_ackers is zero (e.g. on a quiet group, when replicast
ACKs were not requested, or after all expected members have already
acknowledged), an unexpected GRP_ACK_MSG with acked > m->bc_acked
passes less_eq() and unconditionally decrements grp->bc_ackers.
Because bc_ackers is a u16, this wraps to 65535, causing
tipc_group_bc_cong() to permanently report congestion and blocking
all future group broadcasts on the socket.
2. During an active broadcast round (grp->bc_ackers > 0), the sender
transmits packet S and advances grp->bc_snd_nxt to S + 1. Receivers
increment their expected counter to S + 1 upon consuming packet S,
so the only valid ACK value for the current round is strictly
acked == grp->bc_snd_nxt.
However, tipc_group_update_bc_members() initializes each member's
m->bc_acked to prev = grp->bc_snd_nxt - 1 (S - 1 before increment).
This leaves a 2-sequence gap (S - 1 to S + 1) in sequence space.
An incoming ACK is therefore neither rejected as duplicate nor
prevented from decrementing grp->bc_ackers if an unexpected or stale
value (such as S) is received. A member sending acked = S followed
by acked = S + 1 could decrement grp->bc_ackers twice in the same
round, prematurely clearing bc_ackers or underflowing it.
Fix this by:
- Dropping GRP_ACK_MSG immediately if grp->bc_ackers is zero.
- Requiring acked == grp->bc_snd_nxt and rejecting duplicates where
m->bc_acked == acked. Because replicast broadcast rounds are strictly
sequential, only grp->bc_snd_nxt can be acknowledged, and each member
can acknowledge at most once per round.
Note that a related pre-existing issue in tipc_group_delete_member()
(where grp->bc_ackers decrementing to zero upon member departure does
not restore *grp->open or trigger a socket wakeup) will be addressed
in a separate patch. |
| In the Linux kernel, the following vulnerability has been resolved:
nfc: st21nfca: validate ISO15693 inventory length
The ISO15693 inventory helper removes a two-byte prefix without checking
that it exists, then accepts a one-byte remainder before reading data[1] as
the DSFID.
Require the prefix and at least two remaining bytes before copying the UID
data and reading the DSFID. |
