glibc: array overflow in backtrace functions for powerpc

An out-of-bounds write vulnerability was found in glibc when handling signal trampolines on PowerPC. The backtrace function did not properly check the array bounds when storing the frame address resulting in a denial of service or potential code execution. The highest threat from this vulnerabili...

Amazon Linux 2 : glibc (ALAS-2020-1517)

The version of glibc installed on the remote host is prior to 2.26-36. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2020-1517 advisory. In the GNU C Library aka glibc or libc6 through 2.28, the getaddrinfo function would successfully parse a string that contained an IP...

Unspecified Vulnerability in GNU C Library (CNVD-2021-26206)

The GNU C Library glibc, libc6 is an open-source, free C language compiler released under the LGPL license.Library is one of the libraries. A security vulnerability exists in the GNU C Library aka glibc versions prior to 2.2. The vulnerability stems from a missing statement about the unspecified...

The vulnerability of the iconv utility in the GNU C Library (glibc) system library arises from insufficient input validation, allowing attackers to trigger a service failure.

The vulnerability of the iconv utility in the GNU C Library glibc is related to insufficient input validation. Exploiting this vulnerability could allow a malicious actor to cause service failures when invoking the iconv utility with the “-c” option...

The vulnerability of the cosl, sinl, sincosl, and tanl functions in the GNU C Library (glibc) allows a attacker to cause a system failure.

The vulnerability of the cosl, sinl, sincosl, and tanl functions in the GNU C Library glibc is related to the execution of these operations outside the memory buffer boundaries. Exploiting this vulnerability can allow an attacker to cause a service failure by damaging the stack when trigonometric...

The vulnerability of the glibc library lies in its uncontrolled recursion during the search for matches using a regular expression, which allows an attacker to cause a service failure.

The vulnerability of the glibc library is related to uncontrolled recursion during the search for matches using a regular expression. Exploiting this vulnerability can allow an attacker, operating remotely, to cause service interruptions...

DEBIAN-CVE-1999-0199

manual/search.texi in the GNU C Library aka glibc before 2.2 lacks a statement about the unspecified tdelete return value upon deletion of a tree's root, which might allow attackers to access a dangling pointer in an application whose developer was unaware of a documentation update from 1999...

CVE-1999-0199

CVE-1999-0199 affects glibc prior to 2.2. The issue is a missing statement about the unspecified tdelete return value when deleting a tree’s root, which could let an attacker access a dangling pointer in affected applications. Affected: glibc before 2.2. Remediation: upgrade to a version with the...

The string component in the GNU C Library (aka glibc or libc6) through 2.28 when running on the x32 architecture incorrectly attempts to use a 64-bit register for size_t in assembly codes which can lead to a segmentation fault or possibly unspecified other impact as demonstrated by a crash in __memmove_avx_unaligned_erms in sysdeps/x86_64/multiarch/memmove-vec-unaligned-erms.S during a memcpy.

An exploitable signed comparison vulnerability exists in the ARMv7 memcpy() implementation of GNU glibc 2.30.9000. Calling memcpy() (on ARMv7 targets that utilize the GNU glibc implementation) with a negative value for the 'num' parameter results in a signed comparison vulnerability. If an attacker underflows the 'num' parameter to memcpy() this vulnerability could lead to undefined behavior such as writing to out-of-bounds memory and potentially remote code execution. Furthermore this memcpy() implementation allows for program execution to continue in scenarios where a segmentation fault or crash should have occurred. The dangers occur in that subsequent execution and iterations of this code will be executed with this corrupted data.

USN-4416-1: GNU C Library vulnerabilities | Cloud Foundry

Severity Medium Vendor Canonical Ubuntu Versions Affected Canonical Ubuntu 16.04 Canonical Ubuntu 18.04 Description Florian Weimer discovered that the GNU C Library incorrectly handled certain memory operations. A remote attacker could use this issue to cause the GNU C Library to crash, resulting...

In the GNU C Library (aka glibc or libc6) through 2.28 the getaddrinfo function would successfully parse a string that contained an IPv4 address followed by whitespace and arbitrary characters which could lead applications to incorrectly assume that it had parsed a valid string without the possibility of embedded HTTP headers or other potentially dangerous substrings.

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.

...

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.
