A heap buffer overflow in the start_decoder function in stb_vorbis through 2019-03-04 allows an attacker to cause a denial of service or execute arbitrary code by opening a crafted Ogg Vorbis file.

Qemu: qemu-bridge-helper ACL can be bypassed when names are too long

qemu-bridge-helper.c in QEMU 3.1 and 4.0.0 does not ensure that a network interface name (obtained from bridge.conf or a --br=bridge option) is limited to the IFNAMSIZ size, which can lead to an ACL bypass.

An issue was discovered in Asterisk Open Source through 13.27.0, 14.x and 15.x through 15.7.2, and 16.x through 16.4.0, and Certified Asterisk through 13.21-cert3. A pointer dereference in chan_sip while handling SDP negotiation allows an attacker to crash Asterisk when handling an SDP answer to an outgoing T.38 re-invite. To exploit this vulnerability an attacker must cause the chan_sip module to send a T.38 re-invite request to them. Upon receipt, the attacker must send an SDP answer containing both a T.38 UDPTL stream and another media stream containing only a codec (which is not permitted according to the chan_sip configuration).

ImageMagick: a memory leak vulnerability in the function ReadPSImage in coders/ps.c

ImageMagick before 7.0.8-50 has a memory leak vulnerability in the function ReadPSImage in coders/ps.c.

ImageMagick: a "use of uninitialized value" vulnerability in the function ReadCUTImage leading to a crash and DoS

ImageMagick before 7.0.8-50 has a "use of uninitialized value" vulnerability in the function ReadCUTImage in coders/cut.c.

zeromq: stack-overflow on any server protected by encryption/authentication

In ZeroMQ libzmq before 4.0.9, 4.1.x before 4.1.7, and 4.2.x before 4.3.2, a remote, unauthenticated client connecting to a libzmq application, running with a socket listening with CURVE encryption/authentication enabled, may cause a stack overflow and overwrite the stack with arbitrary data, due to a buffer overflow in the library. Users running public servers with the above configuration are highly encouraged to upgrade as soon as possible, as there are no known mitigations.

libssh2: integer overflow in kex_method_diffie_hellman_group_exchange_sha256_key_exchange in kex.c leads to out-of-bounds write

In libssh2 before 1.9.0, kex_method_diffie_hellman_group_exchange_sha256_key_exchange in kex.c has an integer overflow that could lead to an out-of-bounds read in the way packets are read from the server. A remote attacker who compromises a SSH server may be able to disclose sensitive information or cause a denial of service condition on the client system when a user connects to the server. This is related to an _libssh2_check_length mistake, and is different from the various issues fixed in 1.8.1, such as CVE-2019-3855.

exiv2: null-pointer dereference in http.c causing denial of service

http.c in Exiv2 through 0.27.1 allows a malicious http server to cause a denial of service (crash due to a NULL pointer dereference) by returning a crafted response that lacks a space character.

exiv2: uncontrolled memory allocation in PngChunk::parseChunkContent causing denial of service

A PngChunk::parseChunkContent uncontrolled memory allocation in Exiv2 through 0.27.1 allows an attacker to cause a denial of service (crash due to an std::bad_alloc exception) via a crafted PNG image file.

exiv2: integer-overflow and out-of-bounds read in CiffDirectory::readDirectory leads to denail of service

A CiffDirectory::readDirectory integer overflow and out-of-bounds read in Exiv2 through 0.27.1 allows an attacker to cause a denial of service (SIGSEGV) via a crafted CRW image file.

In CISOfy Lynis 2.x through 2.7.5, the license key can be obtained by looking at the process list when a data upload is being performed. This license can be used to upload data to a central Lynis server. Although no data can be extracted by knowing the license key, it may be possible to upload the data of additional scans.

LemonLDAP::NG before 1.9.20 has an XML External Entity (XXE) issue when submitting a notification to the notification server. By default, the notification server is not enabled and has a "deny all" rule.

imagemagick: use of uninitialized value in functionSyncImageSettings in MagickCore/image.c

ImageMagick 7.0.8-34 has a "use of uninitialized value" vulnerability in the SyncImageSettings function in MagickCore/image.c. This is related to AcquireImage in magick/image.c.

imagemagick: memory leak vulnerability in function ReadPCLImage in coders/pcl.c

ImageMagick 7.0.8-34 has a memory leak in the ReadPCLImage function in coders/pcl.c.

imagemagick: memory leak vulnerability in function WriteDPXImage in coders/dpx.c

ImageMagick 7.0.8-34 has a memory leak vulnerability in the WriteDPXImage function in coders/dpx.c.

openjpeg: denial of service in function opj_t1_encode_cblks in openjp2/t1.c

In OpenJPEG 2.3.1, there is excessive iteration in the opj_t1_encode_cblks function of openjp2/t1.c. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted bmp file. This issue is similar to CVE-2018-6616.

In GraphicsMagick before 1.3.32, the text filename component allows remote attackers to read arbitrary files via a crafted image because of TranslateTextEx for SVG.

squid: Denial of service in cachemgr.cgi

Due to incorrect string termination, Squid cachemgr.cgi 4.0 through 4.7 may access unallocated memory. On systems with memory access protections, this can cause the CGI process to terminate unexpectedly, resulting in a denial of service for all clients using it.

SchedMD Slurm 17.11.x, 18.08.0 through 18.08.7, and 19.05.0 allows SQL Injection.

kernel: ppc: unrelated processes being able to read/write to each other's virtual memory

arch/powerpc/mm/mmu_context_book3s64.c in the Linux kernel before 5.1.15 for powerpc has a bug where unrelated processes may be able to read/write to one another's virtual memory under certain conditions via an mmap above 512 TB. Only a subset of powerpc systems are affected.
