environment: Unicode's bidirectional (BiDi) override characters can cause trojan source attacks

A flaw was found in the way Unicode standards are implemented in the context of development environments, which have specialized requirements for rendering text. An attacker could exploit this to deceive a human reviewer by creating a malicious patch containing well placed BiDi characters. The...

DEBIAN-CVE-2021-42574

An issue was discovered in the Bidirectional Algorithm in the Unicode Specification through 14.0. It permits the visual reordering of characters via control sequences, which can be used to craft source code that renders different logic than the logical ordering of tokens ingested by compilers and...

Unicode characters allow malicious code to be hidden from a human reviewer (Bitbucket Server / DC) - CVE-2021-42574

Researchers at the University of Cambridge reported a vulnerability affecting Bitbucket Server / DC where special characters, known as Unicode bidirectional override characters, are not rendered or displayed in the affected applications. These special characters are typically not displayed by the...

fribidi: buffer overflow in fribidi_get_par_embedding_levels_ex() in lib/fribidi-bidi.c leading to denial of service and possible code execution

A heap-based buffer overflow vulnerability was found in GNU FriBidi, an implementation of the Unicode Bidirectional Algorithm bidi. When the flaw is triggered it's possible to manipulate the heap contents, leading to memory corruption causing a denial of service and to arbitrary code execution. T...

SUSE SLED12 / SLES12 Security Update : icu (SUSE-SU-2017:2318-1)

icu was updated to fix two security issues. These security issues were fixed : - CVE-2014-8147: The resolveImplicitLevels function in common/ubidi.c in the Unicode Bidirectional Algorithm implementation in ICU4C in International Components for Unicode ICU used an integer data type that is...

SUSE-SU-2017:2318-1 Security update for icu

icu was updated to fix two security issues. These security issues were fixed: - CVE-2014-8147: The resolveImplicitLevels function in common/ubidi.c in the Unicode Bidirectional Algorithm implementation in ICU4C in International Components for Unicode ICU used an integer data type that is...

The vulnerability of the International Components for Unicode library allows a attacker to trigger a service failure or execute arbitrary code.

The vulnerability of the resolveImplicitLevels function common/ubidi.c in the implementation of the Unicode Bidirectional Algorithm of the International Components for Unicode library is caused by a buffer overflow in the dynamic memory. Exploiting this vulnerability can allow an attacker to caus...
