cvs: Command injection via malicious ssh URLs

CVS 1.12.x, when configured to use SSH for remote repositories, might allow remote attackers to execute arbitrary code via a repository URL with a crafted hostname, as demonstrated by "-oProxyCommand=id;localhost:/bar."

opencv: Heap-based buffer over-write in modules/imgcodecs/src/grfmt_pxm.cpp

In modules/imgcodecs/src/grfmt_pxm.cpp, the length of buffer AutoBuffer _src is small than expected, which will cause copy buffer overflow later. If the image is from remote, may lead to remote code execution or denial of service. This affects Opencv 3.3 and earlier.

opencv: Integer overflow in PxMDecoder::readData function in imgcodecs/src/grfmt_pxm.cpp

In opencv/modules/imgcodecs/src/grfmt_pxm.cpp, function PxMDecoder::readData has an integer overflow when calculate src_pitch. If the image is from remote, may lead to remote code execution or denial of service. This affects Opencv 3.3 and earlier.

opencv: Integer overflow in ReadNumber function in opencv/modules/imgcodecs/src/grfmt_pxm.cpp

In opencv/modules/imgcodecs/src/grfmt_pxm.cpp, function ReadNumber did not checkout the input length, which lead to integer overflow. If the image is from remote, may lead to remote code execution or denial of service. This affects Opencv 3.3 and earlier.

Stack-based buffer overflow in "dnsproxy.c" in connman 1.34 and earlier allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted response query string passed to the "name" variable.

The InfoCard module 1.0 for SimpleSAMLphp allows attackers to spoof XML messages by leveraging an incorrect check of return values in signature validation utilities.

ImageMagick: Use-after-free vulnerability in the DestroyImage function

Use-after-free vulnerability in the DestroyImage function in image.c in ImageMagick before 7.0.6-6 allows remote attackers to cause a denial of service via a crafted file.

Improper Neutralization of Special Elements used in an OS Command in bookmarking function of Newsbeuter versions 0.7 through 2.9 allows remote attackers to perform user-assisted code execution by crafting an RSS item that includes shell code in its title and/or URL.

The ReadWMFImage function in coders/wmf.c in GraphicsMagick 1.3.26 has a use-after-free issue for data associated with exception reporting.

The ReadSUNImage function in coders/sun.c in GraphicsMagick 1.3.26 has a colormap heap-based buffer over-read.

tcpdump: Buffer over-read in print-juniper.c:juniper_parse_header() in Juniper protocols parser

The Juniper protocols parser in tcpdump before 4.9.2 has a buffer over-read in print-juniper.c:juniper_parse_header().

wpa_supplicant: Reinstallation of the pairwise key in the 4-way handshake

Wi-Fi Protected Access (WPA and WPA2) allows reinstallation of the Pairwise Transient Key (PTK) Temporal Key (TK) during the four-way handshake, allowing an attacker within radio range to replay, decrypt, or spoof frames.

wpa_supplicant: Reinstallation of the group key in the 4-way handshake

Wi-Fi Protected Access (WPA and WPA2) allows reinstallation of the Group Temporal Key (GTK) during the four-way handshake, allowing an attacker within radio range to replay frames from access points to clients.

wpa_supplicant: Reinstallation of the integrity group key in the 4-way handshake

Wi-Fi Protected Access (WPA and WPA2) that supports IEEE 802.11w allows reinstallation of the Integrity Group Temporal Key (IGTK) during the four-way handshake, allowing an attacker within radio range to spoof frames from access points to clients.

wpa_supplicant: Reinstallation of the group key in the group key handshake

Wi-Fi Protected Access (WPA and WPA2) allows reinstallation of the Group Temporal Key (GTK) during the group key handshake, allowing an attacker within radio range to replay frames from access points to clients.

wpa_supplicant: reinstallation of the group key (GTK) when processing a Wireless Network Management (WNM) Sleep Mode Response frame

Wi-Fi Protected Access (WPA and WPA2) that support 802.11v allows reinstallation of the Group Temporal Key (GTK) when processing a Wireless Network Management (WNM) Sleep Mode Response frame, allowing an attacker within radio range to replay frames from access points to clients.

wpa_supplicant: reinstallation of the integrity group key (IGTK) when processing a Wireless Network Management (WNM) Sleep Mode Response frame

Wi-Fi Protected Access (WPA and WPA2) that support 802.11v allows reinstallation of the Integrity Group Temporal Key (IGTK) when processing a Wireless Network Management (WNM) Sleep Mode Response frame, allowing an attacker within radio range to replay frames from access points to clients.

GNU Wget: stack overflow in HTTP protocol handling

The http.c:skip_short_body() function is called in some circumstances, such as when processing redirects. When the response is sent chunked in wget before 1.19.2, the chunk parser uses strtol() to read each chunk's length, but doesn't check that the chunk length is a non-negative number. The code then tries to skip the chunk in pieces of 512 bytes by using the MIN() macro, but ends up passing the negative chunk length to connect.c:fd_read(). As fd_read() takes an int argument, the high 32 bits of the chunk length are discarded, leaving fd_read() with a completely attacker controlled length argument.

GNU Wget: heap overflow in HTTP protocol handling

The retr.c:fd_read_body() function is called when processing OK responses. When the response is sent chunked in wget before 1.19.2, the chunk parser uses strtol() to read each chunk's length, but doesn't check that the chunk length is a non-negative number. The code then tries to read the chunk in pieces of 8192 bytes by using the MIN() macro, but ends up passing the negative chunk length to retr.c:fd_read(). As fd_read() takes an int argument, the high 32 bits of the chunk length are discarded, leaving fd_read() with a completely attacker controlled length argument. The attacker can corrupt malloc metadata after the allocated buffer.

ImageMagick: Out of bounds read in ReadOneMNGImage function in coders/png.c

In ImageMagick before 6.9.9-0 and 7.x before 7.0.6-1, the ReadOneMNGImage function in coders/png.c has an out-of-bounds read with the MNG CLIP chunk.
