sqlite: heap-based buffer overflow in multiSelectOrderBy due to mishandling of query-flattener optimization in select.c

In SQLite before 3.32.3, select.c mishandles query-flattener optimization, leading to a multiSelectOrderBy heap overflow because of misuse of transitive properties for constant propagation.

sqlite: integer overflow in sqlite3_str_vappendf function in printf.c

SQLite through 3.32.0 has an integer overflow in sqlite3_str_vappendf in printf.c.

perl: corruption of intermediate language state of compiled regular expression due to recursive S_study_chunk() calls leads to DoS

regcomp.c in Perl before 5.30.3 allows a buffer overflow via a crafted regular expression because of recursive S_study_chunk calls.

curl: Malicious FTP server can trigger stack overflow when CURLOPT_CHUNK_BGN_FUNCTION is used

curl 7.21.0 to and including 7.73.0 is vulnerable to uncontrolled recursion due to a stack overflow issue in FTP wildcard match parsing.

perl: heap-based buffer overflow in regular expression compiler leads to DoS

Perl before 5.30.3 on 32-bit platforms allows a heap-based buffer overflow because nested regular expression quantifiers have an integer overflow.

glibc: stack corruption from crafted input in cosl, sinl, sincosl, and tanl functions

The GNU C Library (aka glibc or libc6) before 2.32 could overflow an on-stack buffer during range reduction if an input to an 80-bit long double function contains a non-canonical bit pattern, a seen when passing a 0x5d414141414141410000 value to sinl on x86 targets. This is related to sysdeps/ieee754/ldbl-96/e_rem_pio2l.c.

glibc: buffer over-read in iconv when processing invalid multi-byte input sequences in the EUC-KR encoding

The iconv feature in the GNU C Library (aka glibc or libc6) through 2.32, when processing invalid multi-byte input sequences in the EUC-KR encoding, may have a buffer over-read.

gdb: buffer overflow while opening an ELF for debugging leads to Dos, information dislosure and code execution

GNU gdb All versions is affected by: Buffer Overflow - Out of bound memory access. The impact is: Deny of Service, Memory Disclosure, and Possible Code Execution. The component is: The main gdb module. The attack vector is: Open an ELF for debugging. The fixed version is: Not fixed yet.

glibc: stack guard protection bypass

GNU Libc current is affected by: Mitigation bypass. The impact is: Attacker may bypass stack guard protection. The component is: nptl. The attack vector is: Exploit stack buffer overflow vulnerability and use this bypass vulnerability to bypass stack guard. NOTE: Upstream comments indicate "this is being treated as a non-security bug and no real threat.

nlist.c in libbsd before 0.10.0 has an out-of-bounds read during a comparison for a symbol name from the string table (strtab).

glibc: regular-expression match via proceed_next_node in posix/regexec.c leads to heap-based buffer over-read

In the GNU C Library (aka glibc or libc6) through 2.29, proceed_next_node in posix/regexec.c has a heap-based buffer over-read via an attempted case-insensitive regular-expression match.

sqlite: heap out-of-bound read in function rtreenode()

SQLite3 from 3.6.0 to and including 3.27.2 is vulnerable to heap out-of-bound read in the rtreenode() function when handling invalid rtree tables.

curl: heap buffer overflow in function tftp_receive_packet()

Heap buffer overflow in the TFTP protocol handler in cURL 7.19.4 to 7.65.3.

curl: TFTP receive heap buffer overflow in tftp_receive_packet() function

A heap buffer overflow in the TFTP receiving code allows for DoS or arbitrary code execution in libcurl versions 7.19.4 through 7.64.1.

libssh2: Out-of-bounds memory comparison with specially crafted message channel request

An out of bounds read flaw was discovered in libssh2 before 1.8.1 in the way SSH_MSG_CHANNEL_REQUEST packets with an exit status message and no payload are parsed. A remote attacker who compromises a SSH server may be able to cause a Denial of Service or read data in the client memory.

libssh2: Out-of-bounds reads with specially crafted SSH packets

An out of bounds read flaw was discovered in libssh2 before 1.8.1 in the way SSH packets with a padding length value greater than the packet length are parsed. A remote attacker who compromises a SSH server may be able to cause a Denial of Service or read data in the client memory.

libssh2: Out-of-bounds reads with specially crafted SFTP packets

An out of bounds read flaw was discovered in libssh2 before 1.8.1 in the way SFTP packets with empty payloads are parsed. A remote attacker who compromises a SSH server may be able to cause a Denial of Service or read data in the client memory.

libssh2: Unchecked use of _libssh2_packet_require and _libssh2_packet_requirev resulting in out-of-bounds read

An out of bounds read flaw was discovered in libssh2 before 1.8.1 in the _libssh2_packet_require and _libssh2_packet_requirev functions. A remote attacker who compromises a SSH server may be able to cause a Denial of Service or read data in the client memory.

libssh2: Zero-byte allocation with a specially crafted SFTP packed leading to an out-of-bounds read

An out of bounds read flaw was discovered in libssh2 before 1.8.1 when a specially crafted SFTP packet is received from the server. A remote attacker who compromises a SSH server may be able to cause a Denial of Service or read data in the client memory.
