Buffer Overflow vulnerability in myQNAPcloud Connect 1.3.3.0925 and earlier could allow remote attackers to crash the program.
In Wireshark 2.2.0 to 2.2.6, the DOF dissector could read past the end of a buffer. This was addressed in epan/dissectors/packet-dof.c by validating a size value.
A buffer overflow was discovered in libxml2 20904-GITv2.9.4-16-g0741801. The function xmlSnprintfElementContent in valid.c is supposed to recursively dump the element content definition into a char buffer 'buf' of size 'size'. The variable len is assigned strlen(buf). If the content->type is XML_ELEMENT_CONTENT_ELEMENT, then (i) the content->prefix is appended to buf (if it actually fits) whereupon (ii) content->name is written to the buffer. However, the check for whether the content->name actually fits also uses 'len' rather than the updated buffer length strlen(buf). This allows us to write about "size" many bytes beyond the allocated memory. This vulnerability causes programs that use libxml2, such as PHP, to crash.
In curl before 7.54.1 on Windows and DOS, libcurl's default protocol function, which is the logic that allows an application to set which protocol libcurl should attempt to use when given a URL without a scheme part, had a flaw that could lead to it overwriting a heap based memory buffer with seven bytes. If the default protocol is specified to be FILE or a file: URL lacks two slashes, the given "URL" starts with a drive letter, and libcurl is built for Windows or DOS, then libcurl would copy the path 7 bytes off, so that the end of the given path would write beyond the malloc buffer (7 bytes being the length in bytes of the ascii string "file://").
In Wireshark 2.2.0 to 2.2.6 and 2.0.0 to 2.0.12, the DHCP dissector could read past the end of a buffer. This was addressed in epan/dissectors/packet-bootp.c by extracting the Vendor Class Identifier more carefully.
libxml2 20904-GITv2.9.4-16-g0741801 is vulnerable to a stack-based buffer overflow. The function xmlSnprintfElementContent in valid.c is supposed to recursively dump the element content definition into a char buffer 'buf' of size 'size'. At the end of the routine, the function may strcat two more characters without checking whether the current strlen(buf) + 2 < size. This vulnerability causes programs that use libxml2, such as PHP, to crash.
In Irssi before 1.0.3, when receiving certain incorrectly quoted DCC files, it tries to find the terminating quote one byte before the allocated memory. Thus, remote attackers might be able to cause a crash.
The compare_dn function in utils/identification.c in strongSwan 4.3.3 through 5.1.1 allows (1) remote attackers to cause a denial of service (out-of-bounds read, NULL pointer dereference, and daemon crash) or (2) remote authenticated users to impersonate arbitrary users and bypass access restrictions via a crafted ID_DER_ASN1_DN ID, related to an "insufficient length check" during identity comparison.
An issue was discovered in adns before 1.5.2. adns_rr_info mishandles a bogus *datap. The general pattern for formatting integers is to sprintf into a fixed-size buffer. This is correct if the input is in the right range; if it isn't, the buffer may be overrun (depending on the sizes of the types on the current platform). Of course the inputs ought to be right. And there are pointers in there too, so perhaps one could say that the caller ought to check these things. It may be better to require the caller to make the pointer structure right, but to have the code here be defensive about (and tolerate with an error but without crashing) out-of-range integer values. So: it should defend each of these integer conversion sites with a check for the actual permitted range, and return adns_s_invaliddata if not. The lack of this check causes the SOA sign extension bug to be a serious security problem: the sign extended SOA value is out of range, and overruns the buffer when reconverted. This is related to sign extending SOA 32-bit integer fields, and use of a signed data type.
In Tor before 0.2.5.16, 0.2.6 through 0.2.8 before 0.2.8.17, 0.2.9 before 0.2.9.14, 0.3.0 before 0.3.0.13, and 0.3.1 before 0.3.1.9, an attacker can cause a denial of service (application hang) via crafted PEM input that signifies a public key requiring a password, which triggers an attempt by the OpenSSL library to ask the user for the password, aka TROVE-2017-011.
An issue was discovered in adns before 1.5.2. It overruns reading a buffer if a domain ends with backslash. If the query domain ended with \, and adns_qf_quoteok_query was specified, qdparselabel would read additional bytes from the buffer and try to treat them as the escape sequence. It would depart the input buffer and start processing many bytes of arbitrary heap data as if it were the query domain. Eventually it would run out of input or find some other kind of error, and declare the query domain invalid. But before then it might outrun available memory and crash. In principle this could be a denial of service attack.
Multiple off-by-one errors in fsplib.c in fsplib before 0.8 allow attackers to cause a denial of service via unspecified vectors involving the (1) name and (2) d_name entry attributes.
Cygwin versions 1.7.2 up to and including 1.8.0 are vulnerable to buffer overflow vulnerability in wcsxfrm/wcsxfrm_l functions resulting into denial-of-service by crashing the process or potential hijack of the process running with administrative privileges triggered by specially crafted input string.

In libosip2 in GNU oSIP 4.1.0 and 5.0.0, a malformed SIP message can lead to a heap buffer overflow in the msg_osip_body_parse() function defined in osipparser2/osip_message_parse.c, resulting in a remote DoS.
WeeChat before 1.7.1 allows a remote crash by sending a filename via DCC to the IRC plugin. This occurs in the irc_ctcp_dcc_filename_without_quotes function during quote removal, with a buffer overflow.
A Stack-Based Buffer Overflow issue was discovered in Digital Canal Structural Wind Analysis versions 9.1 and prior. An attacker may be able to run arbitrary code by remotely exploiting an executable to perform a denial-of-service attack.
The _CFNetConnectionWillEnqueueRequests function in CFNetwork 129.19 on Apple Mac OS X 10.4 through 10.4.10 allows remote attackers to cause a denial of service (application crash) via a crafted HTTP 301 response, which results in a NULL pointer dereference.
