Title
bit7z: Path Traversal via Null Byte Injection from `gcount()` Off-by-One in `restoreSymlink()`
Summary
bit7z is a cross-platform C++ static library that allows the compression/extraction of archive files. Prior to version 4.0.12, a one-byte off-by-one error in SafeOutPathBuilder::restoreSymlink() allows an attacker to craft a .7z archive that, when extracted with bit7z on any non-Windows platform, creates a symlink escaping the intended output directory. Subsequent archive entries extracted through this symlink write arbitrary files outside the extraction directory with the permissions of the extracting process. This issue has been patched in version 4.0.12.

Title
Gimp: gimp:memory disclosure and denial of service via specially crafted pcx image
Summary
A flaw was found in GIMP. This issue is a heap buffer over-read in GIMP PCX file loader due to an off-by-one error. A remote attacker could exploit this by convincing a user to open a specially crafted PCX image. Successful exploitation could lead to out-of-bounds memory disclosure and a possible application crash, resulting in a Denial of Service (DoS).

Title
Music Player Daemon < 0.24.11 Stack Buffer Overflow via pcm_unpack_24be
Summary
Music Player Daemon (MPD) before version 0.24.11 contains a stack buffer overflow vulnerability in the pcm_unpack_24be function in src/pcm/Pack.cxx that allows unauthenticated attackers to corrupt stack memory by triggering an off-by-one write in the PCM decoder plugin. Attackers can issue two MPD commands referencing a malicious HTTP audio source to cause the unpack loop to write 1366 entries into a 1365-entry buffer, overwriting four bytes past the array boundary with three attacker-controlled bytes from an HTTP response body, resulting in daemon termination or potential code execution.

Title
osrg GoBGP bgp.go DecodeFromBytes off-by-one
Summary
A weakness has been identified in osrg GoBGP up to 4.3.0. This impacts the function DecodeFromBytes of the file pkg/packet/bgp/bgp.go. Executing a manipulation of the argument data[1] can lead to off-by-one. The attack may be launched remotely. Attacks of this nature are highly complex. The exploitability is said to be difficult. This patch is called 67c059413470df64bc20801c46f64058e88f800f. A patch should be applied to remediate this issue.

Gogs: Privilege Escalation via Collaboration Access Mode Validation
Summary
Gogs is an open source self-hosted Git service. Prior to 0.14.3, a repository admin collaborator can escalate their privileges to owner-level access by exploiting an off-by-one error in the ChangeCollaborationAccessMode function. This vulnerability is fixed in 0.14.3.

Summary
nanoMODBUS through v1.23.0 contains an off-by-one buffer overflow in the recv_msg_header() function of the Modbus/TCP server that allows remote unauthenticated attackers to write one attacker-controlled byte past the end of the 260-byte receive buffer by sending a crafted MBAP frame whose Length field is set to 255. The overflow corrupts the adjacent buffer-index field of the nanoMODBUS state structure, resulting in denial of service through invalid memory accesses and, on bare-metal and RTOS targets without memory protection, one-byte information disclosure and writes to unintended register addresses on the Write Multiple Registers (FC16) handler path.

RTKLIB 2.4.3 - Off-by-One Out-of-Bounds Read in decode_ssr3 via RTCM3 SSR Message
Summary
RTKLIB through 2.4.3 contains an off-by-one out-of-bounds read vulnerability in the decode_ssr3 function at src/rtcm3.c:1446 that allows remote attackers to trigger a global buffer overflow via crafted RTCM3 SSR messages with attacker-controlled signal mode fields. Remote attackers can exploit this vulnerability by sending malicious SSR correction streams over NTRIP or serial connections to cause denial of service or crash RTKLIB rovers and CORS servers.

CANBoat - Off-by-One Global Buffer Overflow in searchForPgn()
Summary
CANBoat through 6.22, fixed in commit a5a22b7, contains an off-by-one global buffer overflow in the searchForPgn() function in analyzer/pgn.c that allows remote attackers to crash the application. Attackers can deliver a crafted NMEA-2000 message with an out-of-range PGN value over CAN bus or N2K-over-IP to trigger an out-of-bounds array access and denial of service.

Title
Glib: off-by-one error in glib/gkeyfile.c via "g_key_file_get_locale_string_list"
Summary
A flaw was found in GLib. An off-by-one error can occur in the g_key_file_get_locale_string_list function in the gkeyfile.c file when loading a key file with an empty value. This flaw can cause an out-of-bounds access of 1 byte or a denial of service when the out-of-bounds access crosses a page boundary.

Mitigation
Phase: Implementation
Description:
- When copying character arrays or using character manipulation methods, the correct size parameter must be used to account for the null terminator that needs to be added at the end of the array. Some examples of functions susceptible to this weakness in C include strcpy(), strncpy(), strcat(), strncat(), printf(), sprintf(), scanf() and sscanf().
No CAPEC attack patterns related to this CWE.
