Red Hat Enterprise Linux buffer error vulnerability

Red Hat Enterprise Linux versions 6, 7, and 8 have a buffer error vulnerability. This vulnerability stems from multiple migration data processing programs in spice-server using offsets provided by clients from the SPICEMSGCMIGRATEDATA message, without any boundary validation. This can allow...

libsoup: libsoup: Heap buffer overflow via uninitialized length in data-URI base64 decoding

A flaw was found in libsoup. The soupuridecodedatauri function incorrectly treated base64 data-URI payloads as NUL-terminated strings when calling gbase64decodeinplace. If the percent-decoded payload contained embedded NUL bytes, the decoded length could remain uninitialized and be used as the si...

libsoup: libsoup: Heap buffer overflow from WebSocket Pong signal type confusion

A flaw was found in libsoup. When handling an incoming WebSocket Pong frame, SoupWebsocketConnection emitted the ::pong signal with a GByteArray pointer even though the signal is declared to pass a GBytes. Applications connecting a handler that follows the documented GBytes API can trigger heap...

libsoup: libsoup: Heap buffer overflow during WebSocket receive-buffer growth

A flaw was found in libsoup. When max-incoming-payload-size is unlimited 0, SoupWebsocketConnection could grow its incoming GByteArray based on an attacker-controlled frame length until the length wrapped, causing a heap buffer overflow while reading frame data...

libsoup: libsoup: Heap buffer overflow during WebSocket message reassembly

A flaw was found in libsoup. When reassembling fragmented WebSocket messages into a GByteArray, libsoup did not adequately cap total message size against the limits of the underlying buffer type. A remote peer could send fragments that caused size truncation while the implementation still used th...

libsoup: libsoup: Heap buffer overflow during WebSocket client-frame masking

A flaw was found in libsoup. When constructing a masked WebSocket client frame for a very large outgoing payload, size values passed to GByteArray allocation APIs could be truncated while the masking routine still used the full length, causing a heap buffer overflow...

Important: Red Hat Security Advisory: libsoup3 security update

An update for libsoup3 is now available for Red Hat Enterprise Linux 10. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each vulnerability from...

libsoup: libsoup: Heap buffer overflow during outgoing permessage-deflate buffer growth

A flaw was found in libsoup. When the permessage-deflate WebSocket extension compresses a very large outgoing message, truncated size calculations used for GByteArray growth could wrap, causing zlib to write past the allocated buffer and resulting in a heap buffer overflow...

Astra Linux – Vulnerability in libxml-parser-perl

Versions of XML::Parser from 2.45 onwards for Perl may overflow the pre-allocated buffer size, leading to heap corruption double-free or corruption and crashes. The A:utf8 PerlIO layer, using the parsestream function in Expat.xs, may cause the XML input buffer to overflow. This is because Perl’s...

Astra Linux – Vulnerability in xrdp

xrdp is an open-source RDP server. Versions up to 0.10.5 have a heap-based buffer overflow in the EGFX graphics dynamic virtual channel implementation, due to insufficient validation of client-controlled size parameters. This allows for out-of-bounds writes via crafted PDUs. Pre-authentication...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: NFC: pn533 – The UART receive buffer was bound incorrectly. The pn532receivebuf function appends every incoming byte to dev-recvskb, and only resets the buffer after pn532uartrxisframe recognizes a complete frame. A continuous...

Astra Linux – Vulnerability in libxml-parser-perl

XML::Parser versions up to 2.47 for Perl have a heap buffer overflow issue in stserialstack. In the case where stackptr == stacksize - 1, the stack will NOT be expanded. As a result, the new value will be written at location ++stackptr, which equals stacksize. This means that the new value falls...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: net/mlx5e: Fixed the issue where zero-sized buffers were allocated for HV VHCA statistics. The function mlx5ehvvhcastatscreate is called from mlx5enicenable, before mlx5eopen. At that point, priv-statsnch remains zero, because...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: batman-adv: Avoid OGM aggregation when skbtailroom is insufficient. When the OGM aggregation state is toggled at runtime, an existing forwarded packet may have been allocated only with packetlen bytes, while a later packet can...

Astra Linux – Vulnerability in Apache2

A buffer overflow in modproxyhtml in the Apache HTTP Server 2.4.67 and earlier versions allows an attack by a untrusted backend. Users are recommended to upgrade to version 2.4.68, which fixes this issue...

Astra Linux – vulnerability in linux-5.10, linux-6.1, linux-5.15

In the Linux kernel, the following vulnerability has been resolved: netlink: avoid infinite retry looping in netlinkunicast netlinkattachskb checks for the socket’s read memory allocation constraints. First, it performs: rmem skrcvbuf to determine whether the newly allocated rmem value fits withi...

Astra Linux – vulnerability in linux-5.10, linux-6.1, linux-5.15

In the Linux kernel, the following vulnerability has been resolved: iio: light: as73211: Ensure buffer holes are zeroed Since the buffer is copied to a kfifo that can ultimately be read by user space, make sure to zero it out...

Astra Linux – vulnerability in linux-5.10, linux-6.1, linux-5.15

In the Linux kernel, the following vulnerability has been resolved: soc: qcom: mdtloader: Ensure we don’t read past the ELF header When the MDT loader is used in remote proc mode, the ELF header is sanitized beforehand; however, this is not required for other clients. Validate the size of the...

Astra Linux – vulnerability in linux-5.10, linux-5.15

In the Linux kernel, the following vulnerability has been resolved: scsi: target: Fix WRITESAME No Data Buffer crash In newer versions of the SBC specs, we have a NDOB bit that indicates there is no data buffer being written to. If this bit is set via commands such as “sgwritesame --ndob”, we wil...

Astra Linux – vulnerability in linux-5.10, linux, linux-5.15

In the Linux kernel, the following vulnerability has been resolved: usb-storage: alauda: Fix uninit-value in alaudacheckmedia Syzbot caused KMSAN to complain about accessing an uninitialized value within the alauda subdriver of usb-storage: BUG: KMSAN: uninit-value in alaudatransport+0x462/0x57f0...
